No OpenID endpoint found

问题

I'm trying to use the DotNetOpenAuth library to login programmatically from an aspx page. To start with, I'd like to just be able to login using a 3rd party openid provider like myopenid.

My website is an ASP .NET 4 web forms site hosted in IIS 7.5 hosted at port 9980. This port is open (inbound and outbound) in the computer's firewall.

I'm trying to use the OpenIdLogin login control but I keep getting a ProtocolException saying "No OpenID endpoint found"

I've already added this to web.config/system.net

<defaultProxy enabled="true" useDefaultCredentials="true">
     <proxy autoDetect="True" usesystemdefault="True" />
</defaultProxy>

Here's the funny part, the samples themselves are working fine. Any ideas?

-Thanks!

回答1:

Turn on logging and see what it says. It often gives much more detail about why no endpoints were found.

回答2:

Well, I found the problem. It is an issue with the corporate firewall/proxy blocking outbound connections.
