Hello!
I have a HAProxy instance with port 80 TCP and port 443 TCP. The 443 https works great. If I try to connect from the WAN side (pfsenwe with NAT) on port 80 I only get an empty response, but the 443 works great. If I connect internally with local dns resolving to haproxy everything works great. What could cause this?
The part of my config:
frontend http_in
mode tcp
option tcplog
bind *:80
acl linuxSrv hdr(host) -i mail.example.hu
use_backend linux_http if linuxSrv
backend linux_http
mode http
server nginx_http 192.168.0.x:80
