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

Server NGINX
#1

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.

I am using nginx as a ssl offloader in front of HAProxy.

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.
