Server Version#: 1.29.2.6364
Player Version#: 9.10.1.36024
Hi, I have two Shields, 2017 ands 2019 Pro. I have a Plex server running on UNRAID server. Setup on both Shields is virtually identical. 2019 works fine, no issues with streaming from Plex server. 2017 has issues though. When I first wake up 2017, Plex client connect to the Plex server, all menus and libraries are visible, artwork showing up. When I try to play a video, I see an orange circular arrow but nothing happens. I need to exit Plex client, put Shield to sleep and immediately wake it up. The video will then be playing in the background. I can then play any video file from Plex server. If I quit Plex client app, after some time, same issue. No playback. And so on. This does not happen on Shield 2019. It is connected to the same server. Both shields sit on the same network. I checked all config items on both Shields, I see no differences. And yet, 2019 works and 2017 does not 
Also, no issues with playback from web client on Windows etc.
Any ideas? Hints?
I asked on Shield forums but got redirected here. Apparently there were some Plex server issues that had something to do with smb oplocks on NAS but my Plex server is a docker that mounts a local share. As far I see, no smb involved.
I’d appreciate help. Cheers.
