How can you determine if an invalid user certificate has been deployed through MDM?

Problem

When the user certificate deployed in the device becomes invalid (the certificates may be expired or revoked), the web traffic from the device will be blocked. The application will then display an error message indicating that "communications have been blocked due to the invalid user certificate".

For more information about the error, see the Forcepoint ONE Mobile application status page.

The invalid user certificate error will be recorded in the admin logs. For more information, see the Admin logs page.

Solution

If a user reports an error related to an invalid user certificate, redeploy the valid certificate to the devices using MDM.

To learn how to deploy the user certificate to the devices, see the Deploying Forcepoint ONE Mobile for iOS and iPadOS using Microsoft Intune page.
