Can anyone help with setting up my nginx reverse proxy? I have a few sites running on the same box. I am by no means an expert at nginx, I've just got ideas from the internet and got it to work for emby, radarr, sonarr, and lidarr. I would like to have calibre on the same box and working through nginx. Here is my conf section but I am getting this error.

Here is my conf file section

location /calibre {
