Greetings, when I enter Proxmox all of a sudden I can’t log in when I enter my password, I would like to share with you the solution to this problem.


Connect to your server with ssh and paste them respectively, then log in again and it will be fixed.

root@pve1 ~# systemctl restart pvedaemon pveproxy
root@pve1 ~# systemctl restart pve-cluster
