I am having the same issue with my PR2100 and it started around the end of December. I have the same problem with both my Macs. Have not tried down loading from the drive but good to hear it might work if all else fails a I have about 400 movies I am concerned about losing. Plex still functions well.
I chatted once with a rep and she suggested to be sure it is plugged directly into the router. That did not help. I hope to try chatting again soon when I have a few hours to kill.
I thought my unit might be bad but if you are having the same issue, I don’t think that is it. Maybe a Mac OS issue. I will keep you posted and please do the same.
Hopefully someone has a solution.
