The Alert column on the Inventory page shows the warning icon for one or more vCenter Server instances.


The vCenter Server is either unreachable or disconnected from vCenter Cloud Gateway.


  1. Click > to expand the vCenter Server for which the Alert icon is indicating a warning, and verify the status:
    • Disconnected: Indicates that the connection between the vCenter Server and vCenter Cloud Gateway is lost.
    • Unreachable: Indicates that the vCenter Cloud Gateway has been unable to connect to the cloud services for more than 30 minutes.
  2. Check the network connectivity and ensure that the firewall and proxy settings are configured correctly.
  3. Ensure that the vCenter Server and the vCenter Cloud Gateway VMs are powered on.
  4. If the vCenter Server status is Disconnected:
    • Ensure that there is network connectivity between vCenter Cloud Gateway and the vCenter Server.
    • Ensure that the time is synchronized between vCenter Cloud Gateway and the vCenter Server.
  5. If the status is Unreachable:
    1. Verify whether you can access vCenter Cloud Gateway at https://gw-address:5480, where gw-address is the IP address or FQDN of vCenter Cloud Gateway.
    2. If you are unable to access vCenter Cloud Gateway by using the URL, try logging in by using SSH.
    3. If you are still unable to access or locate the vCenter Cloud Gateway VM, delete the vCenter Cloud Gateway VM.
    4. Install a new instance of vCenter Cloud Gateway. See Install vCenter Cloud Gateway.
    5. Connect the vCenter Server instances associated with the deleted vCenter Cloud Gateway VM to the newly installed vCenter Cloud Gateway VM. See Connect Your vCenter Server to vCenter Cloud Gateway.
      Note: If these vCenter Server instances were already converted to subscription, you do not need to convert them to subscription again.
    6. If the issue still persists, contact VMware Support.
