Can't Connect to Proxmox Webinterface After Reboot

[aptiger]

Hi all, I've searched around and found this is somewhat of a common issue, but of the various threads here and else where, and trying vaious solutions, I still can't get connected.

I can't ping it from any computer on my netowrk. I CAN ping it from my router.

I'm pretty new at this. I'm sorry if I overlooked something! Here are my outputs. Any help is appreciated!

Replying here for anyone else possibly facing this issue.

I left out some crucial info, which I'm not sure why I didn't think to mention it in the first place.

Anyhow, I had recently installed Tailscale in a container advertising subnet routes and being used as an exit node.

So if you did that, and are having trouble connecting to your proxmox server's GUI after a reboot, it's possible your new tailscale container is not running!

I had to have access to the physical machine. Login as root.

Type "pct list" to get your list of containers ("qm list" lists VMs) - This lists your containers IDs, Status, and Name.

Type "pct start VMID" (eg. pct start 101) - This still start the container. You should now be able to connect to the WebGUI.

Once you're in, please select your container -> Options -> enable start at boot.
