The server has refused the Secure Socket Tunneling Protocol (SSTP) request. Either a failure response code or no response code was received. The data portion below contains the response code that was received from the server. This is the HTTP status code present in the response. It can be because the web proxy or the SSTP server might be rejecting the connection, the server might not be configured for SSTP or the server might not have a port available for connection.
