Proxmox installation getting into hanged state.

[aditya_prox]

I am very new to proxmox and VM creation. I have installed a bare metal proxmox (using iso file). It was working fine for one week, but over the weekend the UI went into hanged state and ssh also stopped working. Luckily I was close to the system, so I restarted the system. The same thing started happening again and is becoming more frequent. Sometimes only the UI is inaccessible but the SSH keeps working. Is this anything related to my network or incorrect proxmox configuration or hardware compatibility issue.
I can see many threads on hardware compatibility, if somebody can point me in the right direction it will help alot. Also, for more information if anybody can tell me the command to get the hardware details that is relevant to proxmox, I can then share that in the thread for better issue resolution.

Apologies if this happens to be a duplicate, feel free to point to the duplicate.

this inter-mitten networking issues sound more like you might have duplicate IP address assignments in your network. Did you choose a static IP from within the range of IP addresses your DHCP server uses for leases? Can you ping the host when the UI and ssh are not reachable? Are you using the same device to connect when the UI is not reachable but you can connect via ssh?

Yes we have a static IP. I did not understand the second part of the question ( from within the range of IP addresses your DHCP server uses for leases. )
The next time the issue happens I will make sure to check whether ping is happening or not.
Yes I was using the same device from which UI was not reachable but SSH was working as expected.

May you can test ping to the Proxmox VE's static ip and shutdown Proxmox VE host at same time, to verify does ping still reachable once Proxmox VE has been shutdown. To check does the IP address duplicated.

Right. So let me say all that again, but real simple.
An IP conflict is one of many possible causes for the behavior you report, and its very easy to check.

Turn off the proxmox server.
Try pinging it while its off.

If you can ping it while its off ... then there's something else on the same IP ... and that causes intermittent conflicts.
