I'm trying to do the integration of my app with a site (pagseguro.uol.com.br) that manages online payment (like paypal). At the end of the payment process, the site (pagseguro) sends a post to my app with all the info relative to the payment so I can update my app's database, but I'm not receiving that post. According to the pagseguro support this may happen if my app server is configured in a port different from 80 or 443, or if the server needs proxy authentication for comunicating with other applications (pagseguro's app, in this case).
Is the server here in hostingrails configured that way?
Thank you.
Igor.
