Hi, people.

I 'm trying to publish IBM Connections by NGINX allowing access using both HTTP and HTTPS . By HTTPS is working but when I try to access by HTTP I get this error in Google Chrome only:

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<error xmlns="http://www.ibm.com/xmlns/prod/sn">
<code>403</code>
<message>
You are not authorized to perform the requested action.
</message>
<trace/>
</error>

In Firefox there is no error message , but the page does not load correctly . In Internet Explorer it opens normally. Internally it works in any browser. I believe I need some additional configuration in Nginx. My code is:

upstream connections.domain.com {
server 172.16.0.83:443 weight=100000; #LAN/Connections address
server 172.16.0.83:80;
}
server {
listen 172.17.0.14:80; #DMZ/NGINX address
listen 172.17.0.14:443 default ssl;
server_name connections.domain.com;
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 10m;
ssl_certificate /etc/nginx/ssl/connections.cer;
ssl_certificate_key /etc/nginx/ssl/connections.pem;
ssl_verify_client off;
ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers RC4:HIGH:!aNULL:!MD5;
ssl_prefer_server_ciphers on;
location / {
proxy_pass https://connections.domain.com;
proxy_set_header X-Real-IP $remote_addr;
proxy_next_upstream timeout;
}
}

In the Nginx log file, I saw these messages when trying to access from Google Chrome:

"POST /homepage/j_security_check HTTP/1.1" 403 161 "http://connections.domain.com/homepage/login/" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.124 Safari/537.36" "-"

SSL_do_handshake() failed (SSL: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol) while SSL handshaking to upstream, client: 179.213.15.12, server: connections.domain.com, request: "GET /homepage HTTP/1.1", upstream: "https://172.16.0.83:80/homepage", host: "connections.domain.com"

Any help will be appreciated. If you need aditional information, please ask. Thanks you in advance.
