Librespeed shows internal docker IP instead of public IP.

Description

I am hosting my own librespeed instance.
I would expect the site to show my public IP address, but instead it seems to show the internal docker address.

Server

Latest Docker image; Behind a Caddy reverse proxy.

You can configure your reverse proxy to pass the remote IP via headers, e.g. X-Forwarded-For: or X-Real-IP:.

According to Caddy documentation this header is set by default.

This is very interesting: While it shows the internal IP on my phone and laptop it works just fine on my desktop (using the same Firefox version as my laptop)

I found somewhere, that the docker container must run on network mode "host". Has something to do with the NAT which uses internally.
