This site can’t be reached

My Google VM just suddenly refuses connection when i try accessing the instances on the browser.

It throws the following error:

took too long to respond.

Checking the connection
Checking the proxy and the firewall
Running Windows Network Diagnostics

Are you able to ping the VM? Try traceroute if you are on windows or tracert if on Linux.

Yes I can. And the amazing part is that it comes up intermittently and suddenly goes off

Check your server settings if incoming & outgoing is enabled for all IPs

the tracert command shows so many unreached queries:

Looks like there is something blocking incoming requests or your site is not secure

did you solve the problem ??

Try to ping using domain name, you will find different ip is map to domain name. i can able to access using ip. that solved problem for me. request your server admin to map back to your domain.
