Error when configuring reverse proxy to HTTPs

Wed Aug 27 17:37:44 UTC 2014

Hi All,
I'm trying to configure a reverse proxy in Nginx, which receives a HTTP
request and call a HTTPS URL. When we change the config to call a HTTP it
works fine, however it doesn't work with HTTPS. The http_ssl_module is
installed. 

Here is the error:
 <HTML><HEAD>
<TITLE>Invalid URL</TITLE>
</HEAD><BODY>
<H1>Invalid URL</H1>
The requested URL
"/buy-later/buy-later/?customerId=123123", is
invalid.<p>
Reference #9.9cd8f648.1409160431.4f0536
</BODY></HTML

Here goes the current version:
nginx version: nginx/1.4.6 (Ubuntu)
built by gcc 4.8.2 (Ubuntu 4.8.2-16ubuntu6) 
TLS SNI support enabled
configure arguments: --with-cc-opt='-g -O2 -fstack-protector
--param=ssp-buffer-size=4 -Wformat -Werror=format-security
-D_FORTIFY_SOURCE=2' --with-ld-opt='-Wl,-Bsymbolic-functions -Wl,-z,relro'

--with-http_image_filter_module --with-http_spdy_module
--with-http_sub_module --with-http_xslt_module --with-mail
--with-mail_ssl_module

Here goes the config:
  server {
    listen 80;
    server_name localhost;

    location /api/v1/buy-later {
      proxy_pass https://checkout.mysite.com.br/buy-later/buy-later;
      proxy_set_header Host $host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-for $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Proto $scheme;
      proxy_set_header User-Agent $http_user_agent;
    }
  }

Any help is appreciated. Thanks!
