SOLVED: Problem installing via ASUSTOR App Central

[MrAtoz]

Here's the environment:

• ASUSTOR Drivestor2 (Model AS1102T)
  
• ADM v 5.1.0.RN42
  
• Docker Engine v 28.1.1.r54
  
• Jellyfin v 10.11.3.r01
  

Trying the simplest route first, I just installed Docker Engine and then Jellyfin via App Central. When I try to open Jellyfin from ADM, I get a Connection Reset or Connection Closed error. The failing URL is https://192.168.xxx.xxx:28920/ (where 192.168.xxx.xxx is the local IP address for my NAS).

I'm hoping that there's just some NAS configuration item that I'm missing here. I have been running Plex locally on this NAS with no issues.

Thanks for any suggestions on how to troubleshoot!

Update: Working with the maintainer of the App Central Jellyfin package, I was able to resolve this. The problem was that I was trying to launch Jellyfin from the ASUSTOR ADM running over HTTPS, but Jellyfin wasn't configured to accept HTTPS requests. 

Solution:

1. Log into ADM over HTTP
   
2. Start Jellyfin
   
3. Do basic Jellyfin configuration
   
4. Configure Jellyfin to use HTTPS
   
5. Reboot the NAS
   

After this, I was able to log into Jellyfin the usual way over HTTPS.
