Learn how I fix the issue with Proxmox web GUI not being available
I am usually very careful with my hardware devices in my lab. I always avoid any sort of hard reboot, but I mistakenly caused a hard reboot of my Proxmox server, and right after my server start to became unreachable via WebGUI.
The first thought was that I had corrupted the installation OS, and had to start all over from scratch(the worse thing that could happen, ever!), however, I noticed that the SSH was reachable, and then I started to do some research in the forums for some diagnostics commands, using the searching term, “why Proxmox GUI https://ip.pve.server:8006 is unreachable”, to see what I would find.
Many forums threads came up with several ideas, such as:
- Check the certificate
- Check if the local firewall is blocking port 8006
- Run an update of the repositories
After rule out all those options, I realized that the most obvious reason could be that the web service was not running, but I was not quite sure how to verify that, as I do not play around with those commands very often.
The command to verify the Proxmox Web Service status
Then, I went to the official Proxmox documentation resource page, I found the command to show the status of the proxy service :
systemctl status pveproxy pvedaemon
And right as I expected , I got the conclusion that indeed the service was not running, bingo!
Command to Start/Restart ProxMox WebService (proxy.service)
To fix the issue I used the subsequent command
systemctl start pveproxy.service, that flawless brought back up the service, as is possible to see on this output image:
I am still not sure why the service didn’t come up active after the reboot, this never happened before, very odd. Anyway, I wanted to share these finds with you guys, with the aim that would help someone avoid the hassle.
