Can not connect WebOS App

[bm1]

I installed Jellyfin 10.10.7 to Ubuntu 24 + nginix with subdomain. I added this config to nginix config: https://jellyfin.org/docs/general/post-i...oxy/nginx/

It is working perfect on web browser (media.mydomain.com). But when i trying to open with LG TV WebOS app it gives "Can not load. Error code: -27"

I tried to remove

Code:

frame-ancestors: 'self'

from nginx config, but it doesn't work.

What can i do else?
