Describe the Bug

x-forwarded-for header does not appear to be being sent as part of the HTTP/HTTPS connections being made as part of the Test connections for Health validation testing of a HTTP/HTTPS Public Resource.

Environment

OS Type & Version: (e.g., Ubuntu 22.04)
Pangolin/Gerbil: On AWS EC2 VPS - Docker 29.2.1 running top of Ubuntu 24.04 Server
Newt: On home Lab Server - Docker 29.3.1 running on top of Ubuntu 25.10
Pangolin Version: 1.16.2
Gerbil Version: (not sure if this is correct, 1.16.2, I wasn't able to locate a specific version for Gerbil)
Traefik Version: 3.6.11
Newt Version: 1.10.4
Olm Version: (if applicable)

To Reproduce

I have Stalwart Mail Server setup as a Public HTTPS Resource, normal connections to the mail server for JMAP (JSON over HTTPS) are seeing and using the x-forwarder-for header, however connections for the Health Check are being reported as missing the x-forwarded-for header.

Configure Health Check to a backend resource.

Expected Behavior

I would expect all http/https connections made to backend resources will include the x-forwarded-for headers
