# SDP Dashboard Page Is Blank After Upgrading to v6.2.1

After upgrading to v6.2.1, the Dashboard Page in the Admin UI appears blank. All other menus in the Admin UI work correctly. This will happen if there are Gateways in the Collective running earlier versions.

## Products Affected

AppGate SDP v6.2.1.

## Resolution / Suggested Action

This issue is resolved in v6.2.2.

## Workaround and Mitigations

Completing the upgrade of all appliances in the SDP Collective should resolve the issue and the Dashboard Page should become fully functional again. If not all of the appliances can be upgraded at the same time, a customization has been created to resolve this issue in v6.2.1 that will need to be applied to all Controllers in the Collective. The customization can be found [here](https://appgate.my.salesforce.com/sfc/p/3h0000016IT3/a/5d0000001s9j/U7RxOmJtq3wyFUACFXty2m6x2OG.1dMrNlVnjjM6FTs). Please refer to our Admin Guide on [Appliance Customizations](/v1/docs/appliance-customizations-v6-6) and [Customization Configuration](/v1/docs/configure-customizations-v6-6) for more details on applying customizations to your Collective. If you have existing Customizations, you will need to combine them as described in [Adding 3rd Party Executables.](/v1/docs/adding-third-party-executables-v6-6)

Software-Defined Perimeter (SDP) is a security framework that creates a secure boundary around an organization's resources, allowing access based on user identity and context, thereby implementing a zero-trust security model.
