Auto discover seems not to send correct information

Question

Suppose my domain is contoso.com, when I use my browser to access https://lyncdiscover.contoso.com/Autodiscover/AutodiscoverService.svc/root/user?sipuri=[email protected]
THIS IS THE RESPONSE:
{"User":{"Links":[{"href":"https:\/\/lyncdiscover.contoso.com\/Autodiscover\/AutodiscoverService.svc\/root\/user","token":"Redirect"},{"href":"https:\/\/lyncdiscover.contoso.com\/Autodiscover\/AutodiscoverService.svc\/root\/user","token":"Self"}],"SipClientExternalAccess":null,"SipClientInternalAccess":null,"SipServerExternalAccess":null,"SipServerInternalAccess":null}}
It seems to lack information to access the edge server ( from the Internet).
Using the Microsoft Lync Connectivity Analyzer, it shows me this error:
[22/12/2014 17:38:41] [CRITICAL] Reached maximum redirections for 10
[22/12/2014 17:38:41] [ERROR] 
What can be wrong?

Answer 1

Changed my configuration so the reverse proxy uses 4443 on the frontend server . And then visiting https://lyncdiscover.contoso.com/Autodiscover/AutodiscoverService.svc/root/user it now shows:
Server Error
401 - Unauthorized: Access is denied due to invalid credentials.
You do not have permission to view this directory or page using the credentials that you supplied.
This is my current configuration in the reverse proxy:
