ERR_TUNNEL_CONNECTION_FAILED - How to fix the error in Google Chrome
For a while, many users complained about an error loading web pages to their displaying the error message ERR TUNNEL CONNECTION FAILED . This error occurs randomly and only occurs with Google Chrome browser. Today in RedesZone we are going to explain why this error appears while browsing the internet and how to fix it so that it does not happen again and we can browse without problems.
The ERR TUNNEL CONNECTION FAILED error is an error that can occur for a variety of reasons, ranging from incorrectly configuring the domain of the webpage we are trying to visit, conflicting browser data stored in the cache, issues with the service DNS that we are using, and even a proxy configuration error on our computer that is not working well or that is wrong. Then we are going to give you some tips so that you can try to solve it easily.
Automatically detect Internet settings
The first thing to check is if the internet settings are configured to be detected automatically. If we have Windows 10, in the search box typing " Internet options “, This option can be found in the Control Panel.
A window will open with different tabs, in this window we have to go to the tab that puts the connections. Once in this tab we have to go down completely and click where it says " LAN configuration ». Once in " LAN configuration "You have to go to the" proxy server "Located at the bottom of the window that has just opened and uncheck it, if you have the option" Use a proxy server for the LAN ».
Once done, click accept, then restart the computer.
If we find that the problem persists, this may be due to a blockage from our Internet provider or that this service is not available in a certain location. To avoid this we can use a VPN, through the use of a VPN service all traffic will be routed directly to the VPN server, and we shouldn't have any more problems with this error, however, if it continues to appear. occur, we recommend that you perform the following actions in this tutorial to try to resolve it.
DNS configuration empty
To avoid possible errors with the DNS that we have in the cache, it is advisable to empty this cache to redo the request. To perform this action in Windows 10 or any Windows, we need to open a Command Prompt console in Administrator mode. In Windows 10, in the search box we enter the word "cmd".
When it appears, we right click on "Command Prompt" and click on the "Run as administrator" option. A screen will open where at the top left it should say " Administrator: Command Prompt ». Once it has been verified that it has been opened in Administrator mode, we need to write the following:
ipconfig /flushdns
As soon as we run this command, we will get a message saying "The DNS resolver cache was successfully flushed". In the following image, you can see what should come out:
Clear browser data
One of the possible failures of this error while using Chrome is that the browser contains a corrupted data file. By deleting the data, we make sure that Google Chrome does not have corrupted data. For this we need to do the following:
- You press the "control + h" keys, it's a shortcut to go to the history of Google Chrome.
- Once in the "History" window on the left, we must click where it says "Clear browsing data"
- A new window will open, in which we advise you to check that you have checked the following options:
- In advanced settings
- Time range: Always
- Check or verify that all boxes are checked in blue
- Once the above has been verified, click at the bottom right on delete data
- And finally we completely close the browser.
Remove extensions
Another unlikely option that you can try is to remove all extensions that you have installed, even if you have a search bar, we recommend that you remove it. The extension may be to blame for the problem. If you have extensions like noscript or ad blockers, it is possible that these extensions are the culprits, as they are constantly interacting with web traffic and browsing, and maybe with an update of those. here, something went wrong and that is why we have "broken connectivity".
Extensions for the browser are widely used and we have a wide range of options. However, they sometimes generate problems, conflicts that could affect our connection. We must always avoid having more than necessary installed, because they could also slow down our equipment by consuming more resources.
Reset Google Chrome browser
One of the last options would be to restore factory settings . This can resolve if we have an issue at some point in the custom configuration we may have made in our browser. In order to restore the configuration, go to the browser settings and the advanced configuration, at the bottom of the option "Recover the settings and delete" click on "Restore the original default values of the configuration". With this we will leave the Google Chrome browser as it came out of the factory.
Check for adware
Sometimes, we may also experience some type of cyber attack on our browsers. The most common in these cases is adware . It could appear as an additional address bar, for example. It usually infects us when we update it through a link which is actually bogus. In reality, it installs malicious software that damages the proper functioning of the browser.
Therefore, another trick is to check that there is no adware in the browser. We can always use security programs for further analysis. In this way, we will detect annoying security threats that may hamper proper functioning.
If all of the above does not work, we will only have the option to completely uninstall the browser from the “Control Panel”, “Add or Remove Programs” or search for another browser that works properly and allows us to navigate Internet. From RedesZone we recommend the Firefox browser, this browser is also free and allows us to have privacy while browsing, since it does not send any type of information to Google.
