This inscription can appear at the most unexpected moment, which causes justified confusion. Deal with this problem immediately turns out not at all.

Causes

There are many explanations for why the user encountered an internal communication error with Google Chrome. The most common cause is a local network, the settings that have been changed by the user or the software of his PC. If it provides work through a proxy, then this could well lead to such a mistake.

The cache is useful when you need to quickly go to a site that was visited early, but this also leads to failures that cause internal communication errors. To correct the situation, it is necessary to check all possible options and to identify the cause of the problem.

• Clamp on the Win keyboard (with the Microsoft logo) and R.
• In the window that opens, enter inetcpl.cpl and press Enter.
• A new window will appear on the screen, in which you must go to the "Connections" tab and find the "Network settings" button there.
• A new window will open. In it, you need to check "Use a proxy server for local connections". If it already stands, then it is necessary to remove it.
• Click "Confirm" in all open windows and restart the PC.

After turning on the computer, you need to go to the browser and make sure that the internal communication error has disappeared. If nothing has changed, then the reason for disconnection is not connected to local networks.

DNS servers

Changing server settings can help fix the bug. To do this, you need to change the automatically exposed server addresses to those that are officially provided by Google.

To do this, it is enough to perform several manipulations:

• Again, press the combination of Win and R.
• Enter in the appeared line ncpa.cpl and confirm the command input.
• In the window that opens, select the active connection and click it 2 times with the left mouse button.
• A new tab opens, in which you click on the "Properties" button.
• Another window will appear. In it, you need to double-click on "Internet Protocol version 4".
• The third window opens. Here you need to activate "Use the following DNS addresses" and specify 8.8.8.8 as the preferred server, and 8.8.4.4 for the alternative server.
• Confirm all changes.
• Check the browser for an internal communication error.

Clearing saved cookies

As mentioned earlier, storing the history of visits to Internet resources is very convenient. Thanks to this function, the work of webmasters engaged in targeted advertising and many other things is much easier. However, sometimes "cookie" files cause an internal communication error. What to do in this situation?

It's enough just go to the browser settings. After that, go to the personal data section and clear the entire history of visits, including cookies and cache. You need to delete all files. If you clear only those data that have accumulated over the last week, the situation will not change, and the browser will still give out an error.

If none of this has helped, then you should look at the settings of the firewall and antivirus. Sometimes the error disappears after reinstalling the latter. However, before that, it's better to try disabling the antivirus for a few minutes and check the browser.
