Error when configuring reverse proxy to HTTPs

Server NGINX
1

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:

Invalid URL

Invalid URL

The requested URL "/buy-later/buy-later/?customerId=123123", is invalid.

Reference #9.9cd8f648.1409160431.4f0536 </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

–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!

Hi

The error you supplied appears to be coming from the backend itself
so the proxy_pass is actually working

Check with your backend logs to find out if the url requested is not
what you expected… and why the url is invalid

Yes, you’re right. The problem was in the backend. We fixed it up and it
worked.

Thanks.
