Forum: NGINX HTTP/1.1 505 HTTP Version Not Supported Server: nginx/1.2.6

Hi,

I am using nginx as a ssl offloader in front of HAProxy.  The issue I am
having is I get a 505 error on one of the calls I make to Nginx/haproxy. 
If
I make that same call to haproxy directory, I get a 200.

Server OS: centos 5.6
Nginx sever version: 1.2.6
Here is my config:

worker_processes     8;
#worker_cpu_affinity 0001 0010 0100 1000;

worker_rlimit_nofile 70000;
events {
    worker_connections  6144;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    #sendfile        on;
    #tcp_nopush     on;
    #keepalive_timeout  0;
    #keepalive_timeout  65;
    #gzip  on;

 log_format upstream '$remote_addr - - [$time_local] "$request" $status 
'
'upstream $upstream_response_time request $request_time ' '[for $host 
via
$upstream_addr]';

  upstream haproxy {
  # POINT TO HAPROXY:1443
  server 127.0.0.1:1443
  }

    server {
        listen       443 ssl;

        # CERT
        server_name  my.testinstant.com;
  ssl_certificate_key  /etc/nginx/certs/mytestinstant.pem
        ssl_certificate  /etc/nginx/certs/mytestinstant.crt;


        ssl_session_timeout  5m;
        ssl_protocols  SSLv3 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on;
  # SINGLE PROCESS CACHE
  ssl_session_cache  builtin:1000  ;

  ssl_ciphers
!aNULL:!eNULL:!EXPORT:!DSS:!DES:!kEDH:!ADH:!EXPORT:!LOW:!SSLv2:!RC4-MD5:RC4+RSA:DES-CBC3-SHA:AES+RSA:+HIGH:+MEDIUM;


  # POINT TO HAPROXY UPSTREAM
        location / {
  proxy_pass http://haproxy;
        }

  # DEFINE NGINX STATUS PAGE
        location /nginx_status {
            stub_status on;
            access_log   off;
            allow all;
        }

    }

 #error_page   500 502 503 504  /50x.html;
 #location = /50x.html {
 # root   /var/www/nginx-default;
 #}

}

Any help with this would be aprreciated.

Thanks
Rob

To understand what goes on first of all you have to debug what
happens on the wire, either with tcpdump/wireshark, or using nginx
debug log, see http://nginx.org/en/docs/debugging_log.html.

It is a bit out of topic but the 1.5.x tree of haproxy has inbuilt SSL
support (and it works fine) .. so kinda one less moving part in the 
network
setup.

Thanks,  I'll give that a shot. I assume HAProxy 1.5 is still in dev.
