htmlunit or htmlunitwithjs not working in RG

[Venish Martin]

I'm getting below error while running RF code using HTMLUNIT. Kindly suggest what needs to be added as capability or any other way to do it.

MaxRetryError: HTTPConnectionPool(host='false', port=80): Max retries exceeded with url: /session (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x02DEBF90>: Failed to establish a new connection: [Errno 11004] getaddrinfo failed'))

My code is:
