Proxmox has been working fine for about 3 months and had restarted several times properly.

However, I use the Proxmox webpage added a new DNS server 192.168.1.1 and edited the hostname. After applying these changes and restarting, I am no longer able to access the proxmox webpage at https://192.168.1.2:8006

I am able to ping and SSH into the proxmox server.

What should I do to recover the web UI?

If you change the hostname of your PVE node (or it's IP) you need to make sure that you have a correct entry in '/etc/hosts'

Put differently: `uname -n` should be pingable - and should resolve to an IP configured on your PVE node
Check the output of:
Code: 
uname -n
hostname -f
ping -c 3 $(uname -n)

on another node - please consider upgrading to the latest available version - PVE 6.3 was released a bit over a month ago (and we had quite a few updates afterwards as well)

I hope this helps!
