[SOLVED] Login failed. Please try again

[nojah]

Since a couple of days I can't login to the WebGUI as root using Linux PAM standard authentication, just keep getting the folowing message: Login failed. Please try again.
But I can login using the same credentials using SSH.

Any ideas where to start looking?

Hi,

try the following things
* disable all Browser extensions.
* flush the Browser cache.
* restart the pveproxy

I can add that this started when I noticed a backup job for a container was hanged, and still is locked due to backup.
The rest of the VMs ar still running

BTW, none of that helped. I have also tried connecting from different computers.

Look at your Date and Time.
Correct that from Bios.

The time is correct:

Hmm, I found this thread "proxmox backup won't stop"
https://forum.proxmox.com/threads/proxmox-backup-wont-stop.23219/

And after killing the backup PIDs I was able to login to the WebGUI, and then after unlocking PCT 105 I was also able to start it again.

Also got this issue on a fresh install, however am running v6.2-1. I'm able to login with `root` and the same password at the terminal, but using `root` and the same password, with`Linux PAM standard authentication` always gives `Login failed. Please try again`. This happens regardless of browser, or activated extension.

My server time is correct.

I've added some iptables rules as some have suggested:

iptables – I INPUT -p tcp --dport 8006 -j ACCEPT
iptables – I INPUT -p tcp --dport 5900 -j ACCEPT
iptables – I INPUT -p tcp --dport 3128 -j ACCEPT
iptables -I INPUT -i lo – j ACCEPT
iptables -I OUTPUT -o lo – j ACCEPT

But this hasn't worked
