When rebooting my proxmox machine, the gui is accessible for a few seconds, enough for me to login, then crashes. I am not able to ssh into the machine either.
Despite this, the VMs are running and I am able to connect to them over my local network. Oddly enough, I am able to ssh into my proxmox while ssh-ed into one of the VMs. It's like proxmox has built a wall around itself. I've looked through various logs i've found via searches and hven't found any errors. I've tried restarting pve services and used different machines on the network all with the same results. One machine was able to log into ssh but then quickly got disconnected and wasn't able to reconnect.

My router sees proxmox and all VMs on the proper local IP addresses.

I believe the issue is with my router but I'm not sure what has changed.

Hi,

After you are not able to ssh or through GUI could you ping your Proxmox host? if so, please let the ping running and try ssh or log in through the GUI.

please provide us with the following:
Bash:
ip r
ip a
cat /etc/network/interfaces

did you maybe enable the built-in firewall? if you haven't defined the local / management network (correctly), you could definitely see this behaviour (firewall not yet applied on bootup -> connection works, once it's applied it doesn't anymore)

I believe i figured it out. Not 100% sure on the issue but I think it had to do with my router resolving dchp addresses. I restarted my router and my proxmox machine and haven't had an issue since.
