Bought two UniFi Nano HD, tried to connect them to the controller and create a network. Had some issues adopting them, stuck in firmware update mode.
I am running this docker image as the controller.
Instruction said to map port 8080, but I didn't do that since it was busy on my host, so I had mapped it to 8383... Not good.
Finally got them adopted using latest firmware and the instructions here.
Before that I had tried using:
ssh ubnt@[APIP]
# Password = ubnt
mca-cli
set-inform http://[ip of controller]:8080/inform
