Can somebody from Plex help me.

I would like to know if somebody from Plex can help me.
I have the problem that online Cinema Trailers and extra material are not playing (There was a problem playing the item).
I have try in Plex Media Server (Windows 10 Home Ver. 1703 OS Build 15063.483) , Roku (OS 7.7) and Android (7.0) with no success.
Today I update to Plex Media Server 1.8.0 but I still can’t play online movie trailer and extra material.
What can be the problem.

Please do not repeat/cross post.
