Strange playback problem

[Pkanarki 2]

I have a really weird problem:

I use a shield Tv on my lan, mostly for live TV with m3u file fetching .ts files. 

When I livestream on lan via shield, I cannot playback movie from library externally/wan on android app. I can browse the library, but when I choose playback, I get spinning wheel and when I go back all folders/movies etc are gone. It's like connection is lost after that and I cannot logout or anything. After that it is not possible to login anymore from wan anymore until I have connected to lan and then disconnect lan. 

The android app works fine if I am not using the shield on lan.

Problem does NOT happen when I use the chrome browser on my android phone and shield lab at same time.  So strange

I am running latest emby server on Windows 10 Pro, with caddy as reverse proxy with let's encrypt certificates. I have a vague suspicion that it could maybe also might be caddy causing troubles. 

Emby Android app is latest version from Google play. 

 

Best regards

Disregard my topmessage. 

Problem. Was caused by running a zerotier server on the same pc as the reverse proxy(caddy). 

Removing/uninstalling zerotier made playback on android app work again. But I do not know why.
