custom location causes ERR_TOO_MANY_REDIRECTS

[PDiracDelta]

Issue:
using a custom location introduces a ERR_TOO_MANY_REDIRECTS error on my application (which works fine if I use the main forward host without location).

Context (optional):

• Trilium web server docker image
• Nginx proxy manager forwards to the docker container name "trilium" over HTTP
• There is no HTTPS involved whatsoever in my current setup
• All advanced configs in NPM are empty
• The custom location and main location settings in NPM for trilium are identical
• The custom location for "dummy-docker" is working just fine
• connecting Trilium to 192.168.1.52 works
• connecting Trilium to 192.168.1.52/trilium does not work

Checklist

• Have you pulled and found the error with jc21/nginx-proxy-manager:latest docker image?
  • Yes
• Are you sure you're not using someone else's docker image?
  • Yes
• Have you searched for similar issues (both open and closed)?
  • Yes
