Expected input credential was not present

[spectre359]

Hello, I've been following the Testing Two-Way SSL Connectivity Using Postman section of Two-Way SSL (visa.com) and the response I received is 

{
"responseStatus": {
"status": 400,
"code": "9123",
"severity": "ERROR",
"message": "Expected input credential was not present",
"info": ""
}
}

Both the certificate and the Authorization header are present in the request.  Am I missing something? BTW I tried to use the sample C# code at the end of the page and got the same response. Any help is appreciated!

I found out that the problem was Fiddler. It was modifying the request and that's the reason it was not working. The issue is now resolved.
