Need help, nothing has worked.

I’ve been having issues for the past few days. I have Plex just to watch my friends movies. I’m the only one having issues.

I have indirect connection issues, the videos haven’t been playing at all the last few days. When I try to connect is says something went wrong with item. I’ve uninstalled and reinstalled multiple times. I use the Plex Media Server to view his movies. I’ve been searching forums for the last few days and I haven’t had any luck.

I’ve tried the app but I’m not paying money to watch his movies when everyone else is watching it for free. Please help.
