At the same time, the inscription “err_name_not_resolved” was visible from below. How to fix the error? Read on.

Nature of occurrence

Error 105 or “net: ERR_NAME_NOT_RESOLVED” indicates that the system cannot resolve the DNS address of the server that the user requests.

This is caused by the incorrect operation of DNS services, both on your computer and on the server.

That is, the cause of the problems can be both on your site and on the site server, which you cannot access.

In addition, “errnamenotresolved” can only come out in certain programs or browsers, and other applications that use a network connection can work without failures.

What you need to do first

Such problems are sometimes solved by one or two simple actions that must be performed first, and only then, if they did not help, resort to more serious ways.

The problem may be with the router, which for some reason has failed, its reboot, perhaps, will remove the error.

Web pages

They may be any work, because of which they are inaccessible, so it may not be on your computer.

Different devices

Check if all devices get this error. If both phones and computers refuse to load web pages.

If the DNS client service is stopped, then double click on it, start and set the “Automatic” startup type.

Click “OK.”

Clearing DNS Cache

This cache may contain outdated IP of various sites, which is why the computer accesses them and cannot get to the site itself, which changed the IP address.

Perhaps, after clearing the DNS cache itself, the error will disappear.

By itself, clearing this cache does not lead to anything bad, and sometimes solves a number of problems associated with the DNS server, including this one.

  • We put a marker on “Use the following addresses of DNS servers.”
  • We drive in “” in the preferred, “” in the alternative.
  • Save all changes.
  • Again, clear the DNS cache, as described above.
  • Reboot the computer.

The action, allowing to correct this and some more errors in work of the Internet. It is very easy to accomplish with a utility from Microsoft.
