Getting "The remote server returned an error:  500 Internal Server Error" when trying to configure the Retrieve Business Process Variables.  I have set the Forms url as http://localhost/forms and even tried the ip and servername too.  If I hit Test URL is where I get the error.

In Forms config, the workflow server is set as localhost or can be the servername and I can test the connection just fine.  I also have no problems getting to Forms in a browser.

Nothing is configured or set to use SSL but in the error log I see: 

The service '/Forms/api' cannot be activated due to an exception during compilation.  The exception message is: Could not find a base address that matches scheme https for the endpoint with binding WebHttpBinding. Registered base address schemes are [http].. ---> System.InvalidOperationException: Could not find a base address that matches scheme https for the endpoint with binding WebHttpBinding. Registered base address schemes are [http].

The only issue seems to be with Workflow talking to Forms.  Everything is on one box.  Any ideas?

Thanks,

Chris
