fyi, I can't say I understand the fix, but I changed the LAN_NETWORK entry from "10.0.1.1/24" to "10.0.1.0/24,10.0.30.0/29,192.168.118.0/23" and it's working with the -04 release now. I am accessing from the 10.0.1.0/24 network so I would think both the old and the new "Should have" been valid.
Came here because I suddenly couldn't get to the webui for qBittorrent this morning. I had to roll back to version 4.5.5-1-01 for it to work again, the -02 and -03 had the same issue. Is there anything I can add to this recent discussion that would help?
