That's not enough information to give a specific answer. The more details you tell us the higher the chance for a useful reply.

(( While this obviously looks like a network-related problem you may have a problem with your power supply, the chipset on the motherboard, the CPU, the RAM(!), the cabling, the connectors etc. pp. ... ))

Some network related hints - with a different subject, but nevertheless relevant - are in https://forum.proxmox.com/threads/f...can-not-load-the-web-gui-in-a-browser.160091/

Or you may start with giving us some System information, ideally twice (if different): while everything is fine and when you lost connection. In that moment you can log in locally and put the output of each command into a file... to post that contents later.

Does local login work? Or implies your subject a crash of the system? I had read it as "network problem", which might be wrong. If this does not work: is there any information shown on screen?

If a crash happened during the previous boot you can look at the end of the relevant journal like this:

journalctl -b -1  -p warning  -e

For a description of "-b" etc. consult man journalctl.

Additionally you may check all cables and connectors, run memtest86++ over night, check for BIOS/Firmware updates, ...

• pveversion -v

Basic network information:

• ip address show # currently active IP addresses on this machine
• ip route show # currently active routing table
• ip link show # currently active links
• cat /etc/network/interfaces # configuration of the network (and/or ifquery -a for comparison, if they are different)
• cat /etc/resolv.conf # DNS resolver settings
• ping -c 1 -W 1 9.9.9.9 # a simple "ping" to verify outgoing routing
• host quad9.net # a simple DNS lookup to verify reachable DNS servers
