What Should I Do If the System Displays a Message Indicating that the Password Is Incorrect When I Remotely Log In to My ECS?

Solution

Check the network configuration of the ECS and determine whether the fault is caused by a Cloud-Init failure.

Verify that port 80 is bypassed in both inbound and outbound directions in the security group to which the target ECS belongs.

Verify that DHCP is enabled in the subnet to which the target ECS belongs.

After verifying the preceding configurations, restart the ECS, wait for 3 to 5 minutes, and remotely log in to the ECS using a password or key.
