Camera not showing up on NVR list in client

[user_639868941582417_639868941582417]

Camera (823A) and NVR (RNL36) connected to Router. Both show up as connected in client. Camera simply named Channnel01. The camera works in Client and provides llve view in all 3 quality settings. But I can not get it to load on the NVR. Channel01 states connection failed. Before it worked with the camera connected to the NVR, but then I can not easily do an eventual camera security update. Am I doing something wrong?

Never mind, left everything without power for an hour, switched it back on and now it works fine. I did try that before, but just for a minute or two.
