DNS_PROBE_FINISHED_NXDOMAIN on Google App Engine website

Question

For unknown reasons my website on Google App Engine is suddenly not loading anymore on multiple devices and in different browsers. It gives a DNS_PROBE_FINISHED_NXDOMAIN error. I tried restarting the DNS service, changing DNS to Google's, and restarting devices. Nothing helped so far. All other websites load without issues. What could be causing this?

Answer 1

Seems like there are some issues at my domain provider. Their website is giving the same error.

Answer 2

Run following command from cmd

ipconfig /release

ipconfig /all

ipconfig /flushdns

ipconfig /renew

netsh int ip set dns

netsh winsock reset ###( Need to run in administrator mode)

If not successful then

Restart your PC

Answer 3

I've spent weeks fighting with this problem on 2 different unrelated computers, even unable to ping Yahoo.com and having variety of connectivity issues in web browsers, including "DNS_PROBE_FINISHED_NXDOMAIN" and "ERR_NAME_NOT_RESOLVED". I've tried various ipconfig commands, restarting DNS client service, "netsh winsock reset", and other solutions found on the internet.

Finally I realized the only common thing on both my computers was Malwarebytes. After closing/exiting Malwarebytes the problem was solved. I am now able to ping and access every website. The solution, again, at least in my case: close Malwarebytes

I just contacted Malwarebytes support but in the meantime wanted to provide the solution here.
