The request failed with HTTP status 401: Unauthorized

This page describes how to fix the error:

Connection Failed. The request failed with HTTP status 401: Unauthorized.

Cause

This can occur when you try to establish a HTTP connection to an IIS server but the Windows Authentication Role Service has not bee installed.

It can also occur if the IIS server requires a client certificate and this hasn't been provided by the client.

Resolution

Add the Windows Authentication Role Service to IIS:

IIS Windows Authentication Role Service

After Windows Authentication has installed, ensure the required Providers have been added e.g. Negotiate and NTLM.
