Wrong user playing media

[Donmafia 0]

When a normal user (Aleo) is playing media the server think it is the administrator account (Plude) that are playing that media. And it's not only a glitch because when they finish a movie on their account it is actually marked as finished on my admin account etc. This spesefic user is playing the media from outside the network trough a reverse proxy. This have been working for some time noe but just recently it started happening. Not sure from when or what update tho. 

 

Anybody had this problem before? 

 

Server OS: Debian 8
Emby Version: 3.0.5782.0

 

Thanks!
