Traefik needs to forward X-Forwarded-* headers to Authelia so it can
determine the target URL. Without these headers, Authelia returns
"failed to get target URL: missing host value" error.
Added authRequestHeaders configuration to forward:
- X-Forwarded-Method (HTTP method)
- X-Forwarded-Proto (HTTPS/HTTP)
- X-Forwarded-Host (target domain)
- X-Forwarded-Uri (target path)
- X-Forwarded-For (client IP)
This fixes the issue where services returned 401 without redirecting
to the Authelia login page.
