Can't access proxmox ssh or panel web

[basti]

I was accessing through the proxmox administration panel normally, I have not made any configuration and today I can no longer access, neither through ssh nor through the web.
I don’t know what happened
these are some of the commands I have reviewed
Can you me identify what the fault is?

I can only post one image because I am a new user, sorry

Sounds like a network connectivity issue.

Did you have a static IP address configured for that box? Can you ping that box from another machine on the same network?
