Unable to login via GUI after power outage?

[KingTChoka]

Just had a power outage on my server, and now I can't login via the GUI after machine reboot.

I keep getting the `Login failed. Please try again` message. I've tried both `Linux PAM standard authentication` and `Proxmox VE authentication server` login methods.

I can still login via SSH though.

Any thoughts or pointers (using Proxmox v 7.1)? Thanks!

UPDATE: I am able to login if I connect to the GUI from inside one of the VM, but still cannot login from the GUI on my laptop.

Hello,

Please do and provide the following:

- SSH into your PVE server and run `journalctl -f`
- Try log in to your PVE server after (Login failed), stop the journal command Ctrl+C then provide us the output between ([CODE][/CODE])

Update: SOLVED

Background: My datacenter has 2 physical proxmox has 2 nodes. One of the nodes (NOT the one I was trying to login to) had no ethernet connection. After resolving the second node's ethernet connection, the first node can now login.

With only 2 nodes in a cluster, it is recommended to setup a QDevice. [1]
This would prevent such a situation.
