Can't connect via LG C8 app from store

[Atkasi]

Hi there

I have a remote linux server, from which I previously used Emby. Today I decided to try out Jellyfin (installed via Swizzin). I'm reluctant to delete Emby until I get this one working properly though, so note that both apps are installed on the server, however Emby is currently stopped/disabled.

My LG TV is currently on version 05.50.15.

Emby Server seems to be on: 10.8.13

So basically, I can connect just fine via web-browser, I even downloaded the iOS app and can connect to the server from the iOS app. Playback works fine on iOS app as well.

However, when I try to connect via the LG App my TV-screen just goes "black" - or at least it doesn't show anything.

From the server logs I see these related to when trying to access via the TV:

[2024-03-30 21:27:54.945 +00:00] [INF] WS "HOMEIP" closed

The final line is when the TV goes to sleep I suppose.

Anyone have any ideas on what I can try to get this working? I'd like to make the switch from Emby --> Jellyfin, but obviously wont do so if it doesn't work on my TV, which is the main screen for me to watch shows and movies.

Thanks in advance!

Are you using a reverse proxy?

Hope I’m not misunderstanding but I’m connecting via hostname/domain (xx.xx.eu) instead of server IP. However I dont understand why it works via iOS app but not TV, when connecting to the same URL?

Have installed Nginx/Letsencrypt, which I realise might better answer your question..

Yes.  This is what I was asking.

Because this header option can cause issues with WebOS.

Code:

    # Security / XSS Mitigation Headers
    # NOTE: X-Frame-Options may cause issues with the webOS app
    add_header X-Frame-Options "SAMEORIGIN";    # THIS ONE

If you have that in your Nginx config, comment it out.  It isn't required.
