Yeah this is some hardware issue for sure.
I doubt this will help at this point.

What's are your VM settings?
What prefix is your asus router giving you at home.
if its .home or .lan use that pve1.lan is fine
It's easy to change the hostname later.
PS. I personally use a fixed static server IP for my pvx servers but that's me. ie: 192.168.2.10 depends on your DHCP pool.
