Why can't I ping a KEC instance and connect to the specified port program? There are many reasons why the the KEC instance cannot be connected. You can follow these steps for troubleshooting:
Check whether the firewall protocol has been added. The inbound rule ICMP needs to be set on the firewall to allow ping operations.
Check whether the firewall in the KEC instance has been disabled.
Check whether the KEC instance resides in a VPC.
