My jellyfin instance appears in android app search button but can't connect

[mashuuu]

Hello,

I come here because I need help. I run an instance of jellyfin in an docker network behind traefik on my synology nas.

I can access to my jellyfin instance through the web browser (without a valid certificate ) but can't in any other device (phone, windows app)

In the android app when i'm in wifi so in the same network, their is a "Search server" button where i see my instance but when i click on it, i can't login :

   
   

Web browser : 
   

Network : 
   

I tried to follow as I can this : https://github.com/AdrienPoupa/docker-compose-nas
I'm here, if you have any questions !
Thanks you !
