I have a Pinax gunicorn deployment behind a NAT, where the outward-facing Apache server does a ReverseProxy to the gunicorn server. Overall it works well but when I try to log in with OpenID I get an error:
Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request POST /openid/register/. Reason: Error reading from remote server
How can I get Pinax to cooperate with NAT?
