Why Can I Remotely Access an ECS But Cannot Ping It?

Symptom

Possible Causes

A desired inbound rule is not added for the security group, and ICMP is not enabled.

  3. On the Elastic Cloud Server page, click the name of the target ECS.

    The page providing details about the ECS is displayed.

  4. Click the Security Groups tab, expand the information of the security group, and click the security group ID.
