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


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


  1. Click > to expand the vCenter for which the Alert icon is indicating a warning, and verify the status:
    • Disconnected: Indicates that the connection between the vCenter and VMware Cloud Gateway is lost.
    • Unreachable: Indicates that the VMware 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 and the VMware Cloud Gateway VMs are powered on.
  4. If the vCenter status is Disconnected:
    • Ensure that there is network connectivity between VMware Cloud Gateway and the vCenter.
    • Ensure that the time is synchronized between VMware Cloud Gateway and the vCenter.
  5. If the status is Unreachable:
    1. Verify whether you can access VMware Cloud Gateway at https://gw-address:5480, where gw-address is the IP address or FQDN of VMware Cloud Gateway.
    2. If you are unable to access VMware Cloud Gateway by using the URL, try logging in by using SSH.
    3. If you are still unable to access or locate the VMware Cloud Gateway VM, delete the VMware Cloud Gateway VM.
    4. Install a new instance of VMware Cloud Gateway. See Install VMware Cloud Gateway.
    5. Connect the vCenter instances associated with the deleted VMware Cloud Gateway VM to the newly installed VMware Cloud Gateway VM. See Connect Your vCenter to VMware Cloud Gateway.
      Note: If these vCenter 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.
