Error DNS_PROBE_FINISHED_BAD_CONFIG

I have several Wi-Fi connections, one of which works fine, and the other only works for some websites and services such as google.com and Skype. Looking at other sites usually gives me this error:

DNS_PROBE_FINISHED_BAD_CONFIG

I also rarely get the following errors:

 DNS_PROBE_FINISHED_NO_INTERNET DNS_PROBE_FINISHED_NXDOMAIN

Another very strange thing that I came across is that repeatedly refreshing the page often opens it, while it does not apply on every web page.

I found many solutions as a result of long searches on Google & Stack Overflow, but none of them worked. This is not a particular problem for the browser, since the same problem occurs in all existing browsers (e.g. Chrome, Mozilla & IE). I get the same problem on my official computer with Ubuntu OS and on a personal computer with Win10 OS. Meanwhile, I have no problems surfing the web on my mobile phone and other computers connected to the same connection.

Detailed information about the real reason and solution (preferably for both Ubuntu and Win10) will be very useful.

For ubuntu

These errors indicate a problem with the DNS.

  • check cat /etc/resolv.conf DNS settings.

  • And add the following name server in /etc/resolv.conf for temporary or in /etc/resolvconf/resolv.conf.d/head for permanent

 nameserver 8.8.8.8 nameserver 8.8.4.4
  • To add these two name server addresses to resolv.conf
    • run the command sudo gedit /etc/resolv.conf
    • Copy above the two lines of name server folders in the last line of resolv.conf
    • Ctrl + S to save.

  • Note. If you add only the /etc/resolv.conf name server, then when you restart your computer /etc/resolv.conf is in the previous step. Thus, to store these name servers permanently, use the following method:

    • run the command sudo gedit /etc/resolvconf/resolv.conf.d/head
    • Copy above the two lines of the name server and paste /etc/resolvconf/resolv.conf.d/head into the last line
    • Ctrl + S to save.

  • Reconnecting to the Internet

I use Cali Linux. I came across many ways that did not work, except for one. In the terminal, enter: -

 sudo apt-get purge resolvconf

GUI appears, click OK. Reboot your machine. You must have access to the Internet after it starts.
