Went to start a VM that was running the other day, and now it says "The server encountered an internal error. Please retry the request." No other error messages, ID's or indications of anything else wrong. My other 2 VM's seem to be running, but I'm afraid to reboot them. Interestingly, I get the same error when I try to create a new VM from the gallery.
I've tried changing the VM from Basic to Standard, and also changing the size up or down, but it makes no difference. It just won't start. I've tried both from the portal and powershell.
