Subject: [PATCH] fix atitraining 400 bad request from duplicate proxy headers

nginx sent Host/X-Real-IP/X-Forwarded-For/X-Forwarded-Proto twice
(explicit proxy_set_header plus the included recommended-proxy-headers
file), which Apache rejected as a malformed request due to the
duplicate Host header. Removed the redundant explicit headers.
