Installed plex server on Synology ds916+, after updates nothing plays anymore but I see startscreen

Hi, I hope someone can help me?

I bought a monthly plexpass, to see what it was. I manually installed 64 plex server on my synology ds916+ and everything worked great. After the first update I had to reboot my entire NAS because I could not reach the server. After that it worked for a while, but I could not select subtitles while watching a show. That caused three little balls*, so I had to reboot again. After the second update, I cannot play anything anymore. A reboot does not work either. I start the plex player, everythings fine, but when I try to play a video I keep seeing the three little balls, nothing more.

I tried playing it on my samsung smart tv, apple/android products, nothing plays.

Can anybody help me? :slight_smile:

Sincerely,
