SOLVED: Lost access from outside local network

[Sentakki]

Hey everyone,
first thing first, i'm not really good with networking, i have trouble to find where the problem is from.

So, i have a jellyfin server hosted on my windows PC (i know it's not the best). I'm using a dynamic hostname from noip that i refresh every month, i also use their app to automatically update my public ip so i don't have to do anything. Everything was working fine(ish) until two days ago. No one could connect to the server from outside my local network.

 Here are everything i could think off that can mess the jellyfin server :
I have protonVPN automatically open and connect when i turn on my PC (with jellyfin server in the split tunneling, configured in exclude mode)
I have Eset Home Premium as my AV, with rules to let jellyfin server do its thing.
I opened my port in my router ( 8096 to my local IP)

i tried with protonVPN off and eset firewall off too, nothing changes.
I have Jellyseer and flaresolver on a docker desktop (couldn't for the life of me make Jellyseer works outside my network, but that's another issue)
And i have Radarr Sonarr and Prowlarr servers too outside docker.
Everything worked together without any issue, until two days ago i lost jellyfin outside access.

tried to look at jellyfin logs, but nothing comes up about a refused connexion or anything like that
Any ideas ?

Thanks !

Ok update :
For some reason, Eset started to block my router, so nothing was able to contact my PC.
now, it works without protonVPN, but as soon as i connect to the VPN it stopped working. Even tho i added every exe from jellyfin server folder to the exclusion list of protonVPN.

i had to reinstall protonVPN the same day it stopped working, even tho i added back every exe in the exclusion list it doesn't work. does anyone have an idea ?

UPDATE 2 :
OK it works now, i forgot to add back the no-ip software to protonVPN, so it automatically took the IP of the vpn's network adapter, so it wasn't forwarding to my PC anymore.
