Every user of the global network faced a similar problem. The appearance of this information in the browser window spoiled your mood more than once and made you wait for the connection to resume, sometimes to no avail. Now is the time to find out all about the technical information connectionfailure error and figure out how to deal with it.

Causes of occurrence

This error is generalized and does not specify the reason. That is why it becomes almost impossible for a novice user to diagnose and solve a problem. Consider the reasons for such situations while surfing the Internet.

Windows firewall

When you visit the site, packets are exchanged using HTTP technology, which are monitored by Windows Firewall. If the in-house defender doesn't like something or the received data is potentially dangerous, the site loading will be interrupted, and the page will display a connectionfailure error message.

If the problem is still in the firewall, and you are sure that the site is safe, you need to disable the Firewall for a while.

For this:

Attention! After receiving the required information and closing the site, turn on the Firewall again.

Blocking by antivirus

The principle of blocking sites by antivirus is similar to the principle of Firewall. Differences can only be found in the base of untrusted sites, which are compiled based on user experience. To view the content of a web resource, you need to disable real-time protection in the antivirus settings.

Let's look at this process using the example of a regular Windows Defender:

Go to "Settings" - "Windows Defender" and disable active protection.

Attention! Disabling antivirus can lead to computer infection and data corruption. Do it as a last resort!

Browser crash

Sometimes the error is due to incorrect packet handling by the browser itself. Often, to solve this problem, it is enough to restart your Internet browser and try to visit the site again. If unsuccessful, clear the cache.

For this you need:

Consequence of a virus infection

Yes, because of the virus, this is also possible. Check your PC with an antivirus application and follow the further instructions. Kaspersky Virus Removal Tool is recommended for scanning.

No connection to the server

The most common problem that we cannot control. The server hosting the site just doesn't work. It can be overloaded, disconnected, damaged, etc. The only thing the user can do is to contact the technical support service (if there are contacts) and ask how long the access to the resource will be restored.

Problems with the provider

If the above reasons do not fit, and the site opens with the help of the mobile Internet, then the provider has a problem. In this situation, you can also contact the representative of the company of the telecommunication service provider and humbly wait for the restoration of working capacity.

With this connectionfailure error information, you will now know where the "wind is blowing" from and fix the problem yourself in some cases.

The connectionfailure error indicates a system failure to connect to an Internet resource or a complete absence internet connections. Quite often, this problem occurs when scrolling on social networks and during passing online games. This is due to the fact that quite often the servers are overloaded and because of this they “ fall”.

Causes occurrence:

• Access to the site locked firewall;
• Blocks firewall from antivirus;
• Parental control;
• Lock from file hosts;
• Problem with a browser;
• Works on the server itself;
• Incorrect DNS settings;
• Crashes at your ISP, etc.

Checking the firewall

Quite often, mistaking a site for malicious content, Windows firewall submachine gunners blocks this or that site. To solve the problem, you will need disable firewall:

Disable antivirus

Also, an antivirus can cause this problem and we need it disable:

Checking parental controls

Parental controls are used when parents are protecting their child from certain sites (for example, social networks). As a rule, parental control is established through antivirus and disconnects in the appropriate manner as previously described.

Checking the hosts file

The hosts file is used to store any ad filters previously installed by the user. Over time, the user about them forgets but they still work by blocking sites with certain content and ads. To disable the hosts file must go along the path: C: \ Windows \ System32 \ drivers \ etc where you just need to clear text file.

Browser malfunctions

Quite often the connectionfailure error occurs due to malfunctions the browser itself. In this case, there is only one way out, open another browser and go to the resource you are interested in.

Work in progress on the server

Quite often, in order to improve their site, developers carry out certain technical work on it, as a result of which the site may be temporarily unavailable... Therefore, the user only has to wait for the moment when the site will work.

Resetting DNS settings

Over time, the computer's cache, accumulating the remnants of your Internet activity, can become cluttered, which is why some malfunctions in the operation of various servers and in order to fix them it is necessary to clear DNS as follows:

Provider malfunctions

Quite often, the providers themselves have malfunctions in the operation of the server, which is why all sorts of errors occur when loading a particular service. The solution to this problem is quite simple: it is necessary to call to the telecommunications company that provides you with these services and tell you about the problem. Experienced specialists will help you understand and solve it, taking into account the type of the originator of the problem.

Face a Connectionfailure error when navigating to one or more sites. Today we will look at the main ways to solve this error.

The Connectionfailure error has a fairly wide list of reasons for its occurrence, among which it is worth highlighting:

• Antivirus work;
• Carrying out technical work on the requested website;
• Viral activity;
• Unstable work of the site;
• Browser problems;
• Failure of network settings.

Ways to solve the error

Below we will consider the maximum number of ways to solve the error, starting with the most popular one. If the first method did not help you to deal with the problem, go further down the list, and so on until the error is resolved.

Method 1: check if the antivirus is working

First, you need to think about the fact that the connection to the site is being blocked by your antivirus installed on your computer.

1. First of all, completely disable the antivirus for a while, then check the possibility of going to the site in Yandex Browser.
2. If, as a result of disabling the antivirus, the web browser starts working normally, you will need to go to its settings and edit the network parameters, for example, adding the problem site to the antivirus exclusion list.

Method 2: clear cache, cookies and browsing history

Try to go to the requested site from another browser - if the attempt was successful, then most likely the Yandex web browser is to blame for the Connectionfailure error.

Method 3: delete user profile

Next, you should try to delete the current user profile, thereby deleting all the accumulated information by the browser.

Please note that after deleting a user profile, passwords, history, auto-complete forms, user preferences, and other information will be deleted. If you don't want to lose it, be sure to set up browser sync before proceeding.

Method 4: reinstall the browser

A more radical way to resolve the Connectionfailure error that was caused by a malfunctioning browser.

Method 5: eliminate viral activity

Viral activity can also provoke the Connectionfailure error, so you should definitely check your computer for viruses and, if threats were detected, be sure to eliminate them.

It is likely that even after eliminating the viruses, the problem with opening sites in Yandex Browser will not be solved, so you should try reinstalling the browser as described above.

Method 6: fix the hosts file

Viral activity can also change the "hosts" file, on which the opening of links in the browser directly depends. A similar problem occurs as a result of the activity of malware, therefore, after scanning the system for threats, at the same time fix the "hosts" file.

Method 7: flush the DNS cache

Method 8: clean up the Temp folder

Folder "Temp" stores temporary files created by programs on the computer. Using this method, we will delete from this folder all content that may lead to a conflict in Yandex Browser.

Method 9: contacting the provider

If the problem with the Connectionfailure error is observed in all browsers on the computer, and also occurs in relation to far from one site, we recommend that you contact your provider and find out if there are any problems on its side, as well as if there are recommendations for you allowing the problem to be resolved.

Method 10: waiting for the site to resume working

If an error is observed in relation to one site, you should not exclude the possibility that the problem takes place on the side of the site. In this case, you just have to wait a while - as a rule, the problem is solved within a few hours.

Method 11: system restore

If some time ago the browser worked fine, and all sites opened correctly, you should try to perform a system restore by rolling back the computer to the moment when there was no Connectionfailure error in the Yandex browser.

Some of the Yandex browser users may face the inability to access any site and the message "Technical information, Connectionfailure error." In this article, I will explain what this error is, when it occurs and how to fix the Connectionfailure error on your PC.

What is this Connectionfailure error

Usually, an error with technical information is associated with the inability to establish a secure connection with any network resource. Connectionfailure is most often encountered when visiting the site of a social network (Vkontakte, OK, Facebook, Twitter, etc.), and users of various online games also observe it quite regularly.

Causes of the problem

Among the reasons for the error "Technical information Connectionfailure error" in the Yandex browser are the following:

* Malfunctions of the site itself, preventive work on it;
* Crashes in the browser;
* Connection blocking by antivirus;
* Connection blocking by a firewall;
* Malicious activity of virus programs (in particular, the hosts file was changed)
* Failure of provider settings.

How to fix Connectionfailure error
To get rid of the Connectionfailure error, you need to take the following steps:
*Wait a while ... If a resource is out of order for some time, or maintenance work is being carried out on it, then it may not respond to your browser's requests. Here you just need to wait (usually no more than a couple of hours) for everything to work out with Connectionfailure;
*Try using a different browser to enter the site ... There are times when a particular browser is unstable. You can try to clear the cache of your browser, and if it doesn't help, then try to access the resource from an alternative browser;
*Disable antivirus for a while ... After disabling the antivirus, try to go to the required resource and check the connectivity;
*Disable firewall temporarily and try to visit the desired site again. If it is the firewall that is to blame, you can add the required resource to the exceptions and continue working;
*Check your PC for virus programs ... Effective anti-virus tools like Dr.Web CureIt !, Trojan Remover and others will do;
*Check the integrity of the hosts file ... Go to the route Windows / system32 / drivers / etc, open the hosts file with any text editor, and ask if you have something other than the line "127.0.0.1 localhost" (without quotes). If anything else is there, then delete everything else, leaving only the specified line;

*Clean up temporary files. Press the key combination Win + R, type% TEMP% in the line and press enter. Click on "Arrange" at the top left, then on "Select All", then on "Arrange" again, and select "Delete".

*Contact your provider and ask if he had any equipment malfunctions, if the settings were changed, and so on;
*Write a letter to the site developers in which you describe the problem described. It happens that they are simply not aware of the dysfunction that has arisen on their resource

Conclusion

In most cases, the problem "Technical information Connectionfailure error" is caused by failures in the operation of the resource itself, which are quickly eliminated by its creators. Also, the browser and antivirus that block the resource for any reason may be the private culprits of this problem. If you are faced with the problem I described, try the whole complex of the solutions I mentioned, one of them will definitely help you.

The connectionfailure error is caused by a failure in connecting to the resource and does not indicate a lack of Internet connection at all. Frequent victims of the problem are social networks, which from time to time crash and give this error. Gamers also encounter a problem, since the client cannot contact the online server to download data.

Technical info: connectionfailure error

Now let's consider possible solutions to the problem, because usually there is no access to a specific site or a number of pages. The conclusion here is simple, that either your computer is blocking access to the site, or the site itself has a problem. This problem is also observed especially often on sites with SSL protocol, this should be taken into account.

Causes and information - connectionfailure error:

• Access to the site is blocked by a firewall;
• Blocks firewall from antivirus;
• Blocking from the hosts file;
• Browser problem;
• Works on the server itself;
• Reset DNS settings;
• Your ISP crashes.

Each cause has a unique method of elimination, and we will briefly consider all the options presented for a comprehensive troubleshooting.

Blocking by firewall

In this focus, the connectionfailure error is obvious how to fix it, you just need to turn off the firewall, which will lead to the lifting of sanctions on the site. Just before taking this action, you need to make sure that you fully trust the resource, such as social networks.

To disable the firewall, you must:

• Search for the word firewall and go to the found item;

• Go to the section "Enabling and disabling ...";
• Place a check mark in the "Disabled" position in the public network section.

Now check again, maybe the problem has been fixed. Then you can enable it and enable it if you managed to log into the site, since at startup the signatures will be updated and the error will be fixed.

Disable antivirus

It is not necessary to completely disable the antivirus in general, you just need to find out if there is a problem with it. To do this, it is important to deactivate it temporarily and check that the problem has been fixed. Then, when enabled, the filter will be updated and will no longer block the site you need. If this does not happen, you may need to disable the internet firewall or add the site to the whitelist.

Parental control

A similar function is present in many antivirus programs, special utilities, and even a standard Windows function. The super administrator can set certain restrictions on your use of both programs and the network, so that you will not be able to access any particular site. If this is your case, then it is clear how to fix the connectionfailure, just contact the administrator with a request to open access to certain resources.

Blocking from hosts file

There is a common problem when a virus deliberately blocks certain resources or installs a redirect so that instead of the site you see an advertisement or in order to steal your data. There are often cases when the user himself installed filters, and then simply forgot about them. You need to use an antivirus program and clean your computer so that traces of viruses do not spread throughout the system.

Now go to the path C: WindowsSystem32driversetc and make sure that the file is empty or contains the desired settings, but the specified site is not blocked.

Browser issue

So we got to the question, how to fix connectionfailure in the browser. When the browser becomes the cause, this is good, since the problem is easily eliminated and you can easily make sure that it is the cause. You just need to start another browser and go to the resource of interest, and if the problem does not arise, then the reason is in the browser.

In order not to look for the problem directly in it for a long time, you just need to update or reinstall the browser, which will definitely lead to positive results.

Works on the server itself

Quite often, the reason arises through no fault of yours, it is just that the resource is being optimized, updated, or something else like that. Perhaps the site crashed due to a strong DDOS attack, as it could not cope with the load. When everything is fine and scheduled work on the resource is being carried out, then you will be redirected to the appropriate page with information about the launch of the site.

Everything that depends on you, you can simply write to support, for example: to a social network, mail or Skype. Further, nothing is required of you, unless the sappotras ask for help.

Reset DNS settings

Perhaps, as a result of cache cluttering, you have some kind of failures in connecting to certain servers. There may be inaccessible as one site, and all that are located on the territory of a particular country. Resetting is simple:

• Press Win + R and enter cmd;
• Enter the ipconfig / flushdns command.

After completion, close the console and check the result of the action.

Crashes at your ISP

A similar situation is also beyond your control. You can only contact your provider and find out if there are any sanctions against the site and if the network is working properly. Also ask to reboot your switch, which may not work entirely correctly.

Additionally, use a program to clean up cookies and cache, thus making sure that they have not crashed.

After completing the steps, you will be able to access the site, but do not rush to blame your computer or provider for everything, often the problem is in the resource itself. Be patient and the site administrators will launch it as soon as possible.
