After creating the OpenWRT container and assigning an IP address, the ProxMox GUI disappeared.

There is a Thin client hp t610 , with one RJ-45 connector (I did not install the adapter board).
ProxMox is installed on it (6.5.11-4 x86_64).
After creating the OpenWRT container and assigning an IP address, the ProxMox GUI disappeared.
At the same time, OpenWRT worked as usual and had access to it.
As a result, I deleted the container OpenWRT - the problem remained.
I tried to assign different IP addresses for the GUI.

Port 8006 is open and the pveproxy service is running.
Thx for any hint! )

As a result, I completely reinstalled ProxMox - I still can't get into the GUI.
Changed various IP addresses, edited the /etc/network/interfaces file
I tried to replace emp4s0 with emp3s0 - there is NO result.
The output of the ip a command shows not enp3s0, but the same emp4s0.
Confused! )
