Hi,
That happens if BubbleUPnP Server thinks your are connecting from outside your home network.
- Are you running the container with --net=host (host networking) ?
- are you connecting to BubbleUPnP Server with http://<ip>:58050, where <ip> is the local network ip address of your NAS ?
- can you login via ssh and send me (
bubblesof...@gmail.com) the output of command below. Do not post them here
as they contain details on your network.
docker exec -it bubbleupnpserver ip r
docker exec -it bubbleupnpserver ip a
