SOLVED: Nginx http2 issues

[TheDreadPirate]

pulled up "journalctl -xeu jellyfin.service"

it says referenced but unset environment variables at the top, could that be the issue?

That's normal.  Those are optional settings that a default install doesn't use.

I just re-read our docs.  I'll have to do some testing, but I'm pretty sure jellyfin.conf shouldn't be in /etc/nginx/conf.d/.  I have all of my configs in /etc/nginx/sites-available and then I symlink the sites I want to enable to /etc/nginx/sites-enabled.

Code:

sudo su
cd /etc/nginx/conf.d/
mv jellyfin.conf ../sites-available/jellyfin
cd ../sites-enabled
ln -s ../sites-available/jellyfin jellyfin
systemctl reload nginx
