NPM + Docker and Jellyfin

It was for the

> Custom Nginx Configuration

under NPM's proxy host tab. 

That looks similar (not identical) to my nginx conf file for Jellyfin, so wouldn't be entirely applicable to NPM. However, if you're able to edit the conf file within NPM, something like that should work. Doesn't NPM just create the conf file for you anywho?

Yep, it provides scaffolding and then lets you add additional lines (in this case, what I put above).
