From the ale-jwebapp.log we will be seeing the following error,

From the ale-wstunnel.log we will be seeing the following error,

SolutionIn this scenario the communication issue happened because of the incorrect RTLS password in the controller.
Troubleshooting done:
1, Login to Aruba controller GUI and click on Configuration-->Under WIRELESS-->AP Configuration.
2. Select the Aruba AP group and under profiles selected AP.
3. Select the ethernet interface which is in use and then select AP System Profile.
Update the correct RTLS username/RTLS password.
4. Save configuration .
Once after making the above changes we can verify that the data starts received in the ALE feed-reader by executing the following command,
[root@websocket-server ~]# /opt/ale/bin/feed-reader -e tcp://localhost:12001
Attempting to 'connect' to endpoint: tcp://localhost:12001
Connected to endpoint: tcp://localhost:12001
