SOLVED: lan connection error

[lokide]

You can't.  There is no way to ignore those warnings on most TV devices (Roku, Android TV, etc.) or within most Android/iOS apps.

If you're on LAN just use http for devices that stay on LAN?

For devices that come and go, as long as you have NAT loopback enabled or setup custom DNS entries on your router the traffic will stay local when using your domain name.

Ok, that solved my issue. I tried this way before, but I had the idea it wasn't working. After your reply I tried again to remove the "force https", but this time I've restarted the jellyfin server and works.

I'd say we can close this. Thanks for the brainstorming!
