Cannot run nodetool commands after enabling JMX authentication in DSE

I would like to use these two pages to enable DSE Unified Authentication and realize a secure environment. I have tried to configure it but it does not work. How is it as a symptom. When I type nodetool -u -pw status I get

"nodetool: Failed to connect to '127.0.0.1:7199' - FailedLoginException: 'Failed to login. Please re-try.'."

is returned. 2. nodetool status command from node2, which has not touched any files related to DSE Unified Authentication from the initial state, confirms that node1 is working as usual. Please let me know if you have any other suggestions on what else I should try or if I should change a file here or there. If I hit nodetool -h drain, etc. from another node, I get an error, but it is not an Error about Authentication, but a ConnectException.
