Try looking in to he InnerException or even better. The "response string". It would be something like this:
"<HTML> <HEAD> <TITLE>Unknown authorization header</TITLE> </HEAD> <BODY BGCOLOR="#FFFFFF" TEXT="#000000"> <H1>Unknown authorization header</H1> <H2>Error 401</H2> </BODY> </HTML>" this is just an example of an error.
