SOLVED: lan connection error

[lokide]

Hello,

First of all, thank you for jellyfin

I'll try to describe my problem.

Everything works great, I have activated https mode, since I have a domain, I have the ssl certificate by let's encrypt and everything works as expected.

My problem is the following:
Last week there were some problems with internet, so I wanted to connect to jellyfin using the local lan ip address, instead of the domain. Not working.

If I try from the browser, works with no problem, the server is detected, I can login, etc, of course there is an error about the certificate since it's connected with the domain.

If I try from my android phone connected to the wifi, using the jellyfin app or the tv, using the jellyfin app, connected with ethernet, I can't connect to my local server, it only works with the domain connected to the let's encrypt certificate.

The only reason I want to be able to connect using my lan address is that if internet for some reason goes down, I can't reach my homeserver, since the ip is no longer reacheble since there is no internet and in italy we have dynamic ip addresses.

Hope I was clear enough.

To recap:

From Browsers
https://domain:8920 WORKS
https://192.168.1.18:8920 WORKS

From TV/Android using the Jellyfin APP
https://domain:8920 WORKS
https://192.168.1.18:8920 NOT WORKING

So my question is, I'm doing something wrong? Is there a setting to being able to use both my domain address and the local lan one from android/tv apps? Or it's some kind of limitation of the apps? Something about the certificate or maybe there is a setting somewhere I've set wrong?

My homeserver for now runs on windows on latest version, 10.10.6

Thank you.
