app says I don't have emby premiere

[BMNBMN 4]

I don't allow my clients, a Fire TV Stick, and a Google TV box to access the internet, only the local network. But now every few days (it varies), i have the problem that I can't play anything because the app says I don't have Emby Premiere, which I do have. I then have to allow the respective client to connect to the internet for a few seconds and then it works again. Is this intentional or can it be changed? I use the Emby Android app, but I think it also happened on the old app. My server has a constant internet connection where the Emby Premiere license is activated.

 

edit: I forgot to mention that I have the Samsung app on a TV that is also not allowed to connect to the internet, and the problem does not occur here.

Yes this part of the premiere validation, both the server and the client have to validate. You can continue to disallow internet access as long as you allow mb3admin.com.
