Action Steps :-

  1. Ask user what port are they trying to connect the application.

  2. Check if the ICMP is disabled in the Ingress rules. If yes, check with client if it is disabled as a company policy. If this is due to company policy, DO NOT enable it.

  3. Telnet to the given port. If Telnet is working, Give screenshot of Telnet to the user and say there is no network reachability issue. Port (3002) for which the user have raised concern, is not an network issue.

  4. Inform the user that Ping is only used for IP reachability. As ICMP is disabled in Ingress rule as per company's policy, Ping will not work.
