Welcome to the community, Sai! 
It looks like you’re encountering an “Unsupported protocol TLS_SSL” error when using an unspecified MQTT client with MQTT Version 5 on HiveMQ Cloud.
To troubleshoot this issue, consider clarifying the following:
- MQTT Client: Identify which MQTT client you are using. Ensure it supports MQTT Version 5 and is configured correctly.
- Version Compatibility: Test if the error also occurs with MQTT Version 3, as this might help pinpoint if the issue is specific to Version 5.
- Authentication: Verify whether you have set up a username and password for your MQTT clients to access HiveMQ Cloud.
These steps should help you diagnose the problem more effectively.
