SOLVED: Android App not connecting anymore

[damsdams]

Hello, I finally found the problem. Jellyfin censors its own domain name, which means that when you host your own theme—on the same machine or possibly the same domain (to be confirmed)—the connection from the app is impossible, even though it works fine from any browser.

Also, it doesn't generate any errors in the logs or even on the system itself (Debian with Docker in my case). I went through all the logs and found nothing.
