It's showing "The request you have made requires authentication.(HTTP 401)" when executing novac.servers.list()
Any help or guidance will be appreciated.
Also I commented out the logging and warning section of the code. (from line 12 to line 22)

For me, changing user_domain_id at Line#29 to user_domain_name did the trick.
