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.
Try:

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

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

@ekpott
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.
