OpenID Error while testing asp.net app in My Developer Center - intuit-partner-platform

Question

I am testing an application I developed using the .NET Devkit 2.0. In My Developer Center I am trying to run the connection tests in the Testing Your App section of the page. The OAuth test works fine but when I try to test OpenID I am getting an error.
When I click the "Test subscribe to app from Intuit App Center (OpenID)" it brings me to the company connect page, then I select the company, then it brings me to a free trial page of my App.
When I click "authorize" I am getting a 404 Error.
The URL points to: https://myserver.com/Error.aspx?aspxerrorpath=/myapp/OpenIdHandler.aspx
Where myserver is the name of my development server and myapp is the name of my application.
I am able to run the application from Visual Studio without a hitch. It connects and runs as expected but when I try it in the dev center it doesn't work properly.
Are my application settings correct?
Should I be pointing to OpenIdHandler.aspx in this instance?
App settings in the dev center:
App URL: https://myserver/myapp/Default.aspx
Disconnect Landing URL: https://myserver/myapp/Disconnect.aspx
Manage Users URL: https://myserver/myapp/Default.aspx
OpenID URL: https://myserver/myapp/OpenIdHandler.aspx
This is my first run at publishing to the Intuit App Center so any suggestions would be a huge help. I'm not even sure if the settings in the dev center are the problem or not.
Thank you

My firewall was not set up properly so it was not allowing any traffic to hit the desired pages of the site. Seems very curious to me that I was able to go to the default page but no others. Any way, it works now.
