Docker motioneye (pi2) works, but can't add to motionOS hub

Hello,

I've a pi2 running motioneye in docker with this command:

docker run --name="motioneye"
-p 80:8081
-p 8765:8765
--hostname="motioneye"
-v /etc/localtime:/etc/localtime:ro
-v /etc/motioneye:/etc/motioneye
-v /var/lib/motioneye:/var/lib/motioneye
--restart="always"
--detach=true
--device=/dev/video0
ccrisan/motioneye:master-armhf

For the host IP I can access the stream, all good.

When adding to the motionOS hub (which has 3 motionOS pi0's in OK) the MJPEG network camera is found, but upon adding it is solid bright green, changing to solid grey after a bit.

On the pi2: docker version Client: Docker Engine - Community Version: 20.10.6 API version: 1.41 Go version: go1.13.15 Git commit: 370c289 Built: Fri Apr 9 22:46:18 2021 OS/Arch: linux/arm Context: default Experimental: true

motionEye Version | 0.42.1 Motion Version | 4.2.2 OS Version | Debian 9.12

On the hub: motionEye Version | 0.42.1 Motion Version | 4.2.2+gitUNKNOWN OS Version | motionEyeOS 20200606

Would anyone have anything to try / info req.?

Cheers, Ben
