Possible Cause

Check the following items to troubleshoot the fault:

Solution

  1. Check the DNS configuration.

    1. Log in to the management console.
    2. Under Computing, select Elastic Cloud Server.
    3. Click the name of the ECS.

      The ECS details page is displayed.

    4. Click the VPC name.

      The VPC console is displayed.

    5. In the VPC list, click the VPC name.
    6. On the Subnets tab, check whether the DNS server addresses are correct.

    4. Locate your user group and click Assign Permissions in the Operation column.
    5. To install the Agent, you must have the following permissions:
      • Global: Security Administrator
      • Region: ECS CommonOperationsr or BMS CommonOperations, and CES Administrator or CES FullAccess
