I have found why my NanoPi - M4V2 SBC was not working well with my QHY cameras running INDI-SERVER.
It seems if I use a QHY main camera and use a ZWO guide camera, something goes very wrong as the QHY camera goes offline and the indi connection to the QHY camera goes down.
If I use ONLY QHY cameras or ONLY ZWO Cameras, no issues.
Yes, I had the same issue with Astroberry as well as my ubuntu setup. It works great as long as you don't mix the two. I picked up a QHY guidescope and resolved my issues with my QHY main camera setup.
