SikuliX / RobotFramework / robotframework-SikuliLibrary: problems to get it running

Trying to integrate Sikuli with Robot Framework (python). Hence, I am trying to use this Library "robotframework-SikuliLibrary". The site provides with the demo, it threw error when I ran the test. Here is the error

----- pybot testsuite_clickin.txt
[ WARN ] Test get_keyword_names failed! Connecting remote server at http://127.0.0.1:47630/ failed: [Errno 111] Connection refused
[ WARN ] Test get_keyword_names failed! Connecting remote server at http://127.0.0.1:47630/ failed: [Errno 111] Connection refused
[ ERROR ] Error in file '/home/xx/Desktop/robotframework-SikuliLibrary-master/demo/click_in/testsuite_clickin.txt': Initializing test library 'SikuliLibrary' with no arguments failed: Failed to get_keyword_names

And here is the error from the Sikuli_java_stdout

I tried to walk thru the same issues in this forum, but they don't seem applicable.

Any helps from here would be very much appreciated. Thank you!
