Why Does a Node Fail to Be Connected to the Internet?
If a node fails to be connected to the Internet, perform the following operations:
Check Item 1: Checking Whether an Elastic IP Address Has Been Bound to the Node
Log in to the ECS console and check whether the ECS has been bound to an elastic IP address.
As shown in the following figure, if there is an IP address in the elastic IP address column, an elastic IP address has been bound. If there is no IP address in that column, bind one.
Check Item 2: Checking Whether a Network ACL Has Been Configured for the Node
Log in to the VPC console and choose Network ACL from the navigation pane. Check whether a network ACL has been configured for the subnet where the node is located and whether external access is restricted.
