I should have noted that, but the 0.0.0.0 put me off. I’m not sure what’s using 8080, so I mapped 8090:8080.
The container now runs. Hopefully that would cause many problems. I see it used by the access points from https://hub.docker.com/r/linuxserver/unifi-controller:
Alternatively to manually adopt a device take these steps:
ssh ubnt@$AP-IP
mca-cli
set-inform http://:8080$address/inform
In the meantime, I’ll try to find what app is currently using 8080.
