Jellyfin remote access not working

[not cheating]

Essentially jellyfin is all set up and works just fine locally however if I were to try from my phone on my cellular service I could not gain access. I'm currently using an att fiber modem/router and have port forwarding and all relevant settings established since I had a similar issue with Plex but I used the settings mentioned above to fix it (I hate how I have to pay a subscription to use their app hence why I'm switching to jellyfin) 

any other suggestions to getting this to work ?
