I'm glad you found a solution to your problem. I can confirm this was not how my diagnostics went. It was basically a 1 hour break for me while I beat my head against concrete (because that was a softer and more yielding thing to beat my head against) and when I returned everything was fine. Thankfully nothing like that has happened since.Very late but I ran into this same issue. Don't know if it was sheer luck or a solution but after and hour of frustration I assigned a new IP in my router, enabled DHCP in the VM, rebooted the VM and it took the IP, then disabled DHCP in the VM again. Created an account just to post this and it could be entirely wrong but maybe it will help someone else.
