I have an Azure Linux VM running MySQL, which has stopped responding for the past 24 hours - ping, SSH, MySQL and everything else timeout when trying to connect to it. Yet the status shows as 'Running' normally in the portal.
I've tried restarting the server, stopping/start the server, resizing it. All complete successfully, but make no difference. I also detached the VHD from the VM and created a new VM with it instead, but the new VM has the same problem. I guess this means the problem is with the VHD itself. It had been running well for a couple of months before this. The only change recently this was adding a new, blank WordPress database for a new site with no traffic yet.
Is there anything I'm missing that could cause such a problem, or any way to solve it? It's incredibly frustrating as all my sites are down with no fix in sight :(
