Accessing services of LibreELEC machine from outside my network

I have instaled Jellyfin server on my LibreELEC machine and can I can access it at machine-ip:8096 inside my network.

To access from outside my network I have configured port-fowarding for this port on my router but I is not working, do I have to do anything in LibreELEC to accept this external connection?

Thanks in advance!

You need a static IP to access your router from internet. Google "static IP <YOUR_ROUTER_MODEL>".

This is not a problem, I already use FreeDNS and I access my Raspberry-Pi from internet via port-fowarding without problem. I'm trying to do the same to access to my Jellyfin@LibreELEC but is not working, It seems to me that it is blocking external connections because it works inside my network, is it possible?

Solved, the problem was on my router.
