Server not found!

After windows 10 update, only edge can access the internet and Firefox or chrome cannot have the connection. I have checked the firewall, Firefox is already in the permission list. Theres no other security software. Does anyone have the same experience and share any solution? Thanks a lot.

Type about:preferences#advanced<Enter> in the address bar.

Under Advanced, Select Network. Look for Configure How Firefox Connects and press the Settings button. If you are using a proxy, make sure those settings are correct. If there is no proxy, first use No Proxy. If there is a problem, then try System Proxy.


Some problems occurs when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see

None of the above worked. i have also tried many more fixes and none work either.

As a test, disable your protection programs.

I tried that disabling both Kaspersky and Windows VPs. I got no change. I also worked with Kaspersky on the problem with no results after trying their fixes.

Hello to all, any luck if you change the default DNS servers to Google DNS servers ?

see : http://solverbase.com/w/Windows_10:_Changing_DNS_Servers

you can change it back again to default (Obtain to DNS address automatically) if does not work OR check it from time to time to change it back to default (Obtain to DNS address automatically) even if the issue solved with that way :-)

thank you
