Good evening, I am facing a strange issue. I installed Proxmox on an old pc (old Asus M4A78LT-M LE motherboard, upgraded with a 512GB SSD and 16GB ram) and everything seemed to work. I have now 2 VMs running, a Debian server and a Truenas distro (with a lot of disks passed directly to the VM).
Everything is basically working, except that after a couple of hours running, proxmox becomes unreachable (both SSH and web GUI). My journal -f shows a lot of "authentication failure", even though I am perfectly able to login with root user both in SSH and web gui. I also changed password, removing special characters in it, restarted the services and the server many times, but I can't understand which is the problem. Here's the output of journal -f:
