I'm building a highly available site using a multiple HAProxy load balancers, Nginx web serves, and MySQL servers. The site needs to be able to survive load balancer or web servers nodes going offline without any interruption of service to visitors. Currently, I have two boxes running HAProxy sharing a virtual IP using keepalived, which forward to two web servers running Nginx, which then tie into two MySQL boxes using MySQL replication and sharing a virtual IP using heartbeat. Everything is working correctly except for SSL traffic over HAProxy. I'm running version 1.5 dev12 with openssl support compiled in. When I try to navigate to the virtual IP for haproxy over https, I get the message: The plain HTTP request was sent to HTTPS port. Here's my haproxy.cfg so far, which was mainly assembled from other posts:

global
        log 127.0.0.1 local0
        log 127.0.0.1 local1 notice
        # log 127.0.0.1 local0
        user haproxy
        group haproxy
        daemon
        maxconn 20000

defaults
        log global
        option dontlognull
        balance leastconn

        srvtimeout 60000
        contimeout 5000
        retries 3
        option redispatch

        bind :80
        bind :443 ssl crt /etc/pki/tls/certs/cert.pem
        mode http
        option http-server-close
        option forwardfor
        reqadd X-Forwarded-Proto:\ https if { is_ssl }
        reqadd X-Proto:\ SSL if { is_ssl }
        server web01 192.168.25.34 check inter 1s
        server web02 192.168.25.32 check inter 1s
        stats enable
        stats uri /stats
        stats realm HAProxy\ Statistics
        stats auth admin:*********

Any idea why SSL traffic isn't being passed correctly? Also, any other changes you would recommend? I still need to configure logging, so don't worry about that section. Thanks in advance your help.
