What Should I Do If Error Code 1006 or 1000 Is Displayed When I Log In to an ECS Through the Management Console?

Symptom

When I attempted to remotely log in to an ECS using VNC, the system displayed error code 1006, as shown in Figure 1.

Possible Causes

• The ECS is abnormal.
• Another user has logged in to the ECS.
• No operations are performed on the ECS and it is automatically disconnected.

Troubleshooting

1. Log in to the ECS again using VNC.
   • If the login is successful, no further action is required.
   • If the fault persists, go to 2.
2. Check whether the ECS is normal.

   Error code 1006 is displayed if the ECS is stopped, deleted, being migrated or restarted, or encounters a connection timeout.

3. Check whether another user has logged in to the ECS.

   If yes, you can log in to the ECS only after that user logs out.
