Diagnosis

• Navigate to CMC UI
• Choose the cluster where the issue is residing
• Navigate to Cluster configurations
• Choose the Data Agent section under Server Configurations
• Retrieve the hostname and the port used for connectivity from the below:

Analytics Public Hosts and Ports
Loader Public Hosts and Ports

• Perform a telnet on the retrieved hostname and port number from the Data Agent machine

telnet <hostname> <port number>

• The connection does not appear to be established and not showing connected message

Solution

Check with the customer Networking team to allow outbound traffic on the desired hostnames and port number.
