Error 500: hostname lookup 'pve2' failed - failed to get address info for: pve2: Name or service not known

I built a second PVE and named it pve2; it's now the primary. I had some VMs that I want to trash but can't. I get the following:

Error 500: hostname lookup 'pve2' failed - failed to get address info for: pve2: Name or service not known

/etc/hosts

GNU nano 5.4                                              /etc/hosts                                                       
127.0.0.1 localhost.localdomain localhost
10.20.20.5 pve pve.network.lan

root@pve:~# hostnamectl status
   Static hostname: pve

How can I resolve this?

Thank you!

I would add the new node into DNS and/or hosts file

Note: The hosts should be as the following:

127.0.0.1 localhost.localdomain localhost
10.20.20.5 pve.network.lan pve

This is the only Node now, the hosts file currently shows what you had suggested.

What I did to fix:
rm -rd /etc/pve/nodes/pve2

There was no data in there on those VMs.
