nginx not forwarding requests to backend servers.

[Brian Pugh]

Still not working.

Logs show:

2016/07/27 11:59:35 [warn] 28038#28038: *3 upstream server temporarily
disabled while reading response header from upstream, client:
192.168.254.202, server: myapplicationsite.net, request: "GET / HTTP/1.1",
upstream: *"http://192.168.155.120:443/ <http://192.168.155.120:443/>"*,
host: "myapplicationsite.net"

Why does it show http:// with :443 here?

Here is my updated config:

http {
    upstream mysiteapplication.net {
        # Use ip hash for session persistance
        ip_hash;
        server backendappsite1:80;
        server backendsiteapp2:80;
        server backendsiteapp3:80;

        # The below only works on nginx plus
        #sticky route $route_cookie $route_uri;
}
   upstream ssl_mysiteapplication.net.net {
        # Use ip hash for session persistance
        ip_hash;
        server backendappsite1:443;
        server backendappsite2:443;
        server backendappsite3:443;

        # The below only works on nginx plus
        #sticky route $route_cookie $route_uri;
}

Crasyangel - I am not sure where I am supposed to put this:

u.default_port = 80; in ngx_http_upstream_server

I tried it inside my http upstream block and got a message about

unknown directive "u.default_port"

Here is my updated default.conf:

server {
    listen       443 ssl;
    server_name  myapplicationsite.net;
    keepalive_timeout 70;

    ssl_certificate     /appssl/fd.crt;
    ssl_certificate_key /appssl/lb.key;
    ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers         HIGH:!aNULL:!MD5;

    location / {
        proxy_pass   http://ssl_test-resolve.cspire.net;
        proxy_set_header HOST test-resolve.cspire.net;

    }
    }
