I had a working pi-hole. But suddenly it stopped functioning. I have reinstalled, configured the network, but cannot open the pi-hole configuration page. In the docker logs, pihole starts correctly. I also noticed that when I change anything in the settings of the OMV network card (Network >> Interfaces) I lose connection to OMV and it returns after restarting the Raspberry Pi with the settings I changed. The address 192.168.1.245 does not respond, does not ping, the page does not open. Help me please.
