I am using Jenkins 1.638 with Rational Build utility plugin 6.0 to connect to the RTC URL with the given credentials. But when i test connectitivity with the provided RTC i am facing below error:
"This client received an unexpected response. The URL of the server you are trying to connect to is either invalid, older than your client and not compatible, or behind a proxy or firewall that requires authentication. Please contact the system administrator to determine the correct URL or server version, and download the appropriate client. "
