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.
    Figure 1 Port 80
  • 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.
