Movie/Shows are not working via infuse or plex

Hi… I am unable to add hulu movies/shows on plex media server. I read qnap tutorial https://www.qnap.com/en-us/how-to/tutorial/article/use-a-qnap-turbo-nas-as-a-plex-media-server-to-stream-your-movies-and-videos/ on how to stream media via plex it suggested me to add the titles and then it can be streamed but it didn’t work for me like that. I usually get my list of movies,shows etc from screenbinge https://screenbinge.com/channels/best-vpns-for-streaming/ and they also didn’t write anything about qnap or general NAS system used for streaming content. I am using a commercial vpn with my router. On my PC, Android TV, and iPhone all the apps are working its just plex which I can’t understand whats wrong with it.

HELP!

It’s clearly something with the app since it works with Infuse 5, via Safari on my MacBook and iPhone. Not a single buffering. It’s just movies somehow… I would love to fix that… It’s not useable at this point.

Any help would be really appreciated.
