Can a high CPU spike kill my Azure VM?

Through investigating I realized after a high CPU spike, my VM restarted on its own and since then I am unable to remote to it. Testing the connection on the Azure portal shows I should be able to connect to the VM but I am not able to. Has anyone ever experienced this issue? Any way to resolve it?

I followed the Azure RDP troubleshooting doc and none of those steps worked.

Update: The issue was resolved, detaching the disc and attempting a repair seems to have narrowed it down to a particular VPN software that had taken over the ports for connection. It was uninstalled, the disk reattached and connecting was once more possible

    Hi @Anonymous ,

    I haven't noticed a restart caused by high CPU load on a VM so far.

    The VM restarted in Azure or it's just a restart of the OS of the VM?

    Maybe it's worth to redeploy the VM on a new Azure host. You can do this in the Azure portal:
