your system is quite outdated.
We support only the current Proxmox VE version.
So upgrade to the current version.
It would be nice but unfortunately there is no opportunity to quickly upgrade, tell me what to look for?

This looks like hardware is failing. Please check that the NIC, PSU, HDD ... of that server is functioning properly.
