webroot / nginx config

[sub]

Hello,

I'm trying to get nginx reverse proxy in front of NextPVR. It works WITHOUT a webroot, however when I try to create anything it fails.

For example...

https://mydomain.com > works and the NextPVR login screen displays
https://mydomain.com/npvr > does not work, nor does ny other acronym i've tried

HELP! Can I set a webroot somewhere, or tell me one which work (if hardcoded)

It should support any webroot. What happens when you try? Is it just somethings that don't work, or you can't even get to https://mydomain.com/npvr/index.html?
