When i try to install agent it was displayed error like this :
Error during agent install ([Errno 111] Connection refused).
If you need to make changes, you can press "Retry" and installation will continue from the last attempted node.
What can cause this error please help
Maybe this is problem with Credentials which I enter in installation form but i am beginner in ubuntu system so what I should write in Username field ? I add that I have one cassandra's node on localhost
