You may see an error in the Jamf School dashboard that says: "The '[server token]' (ASM token) was rejected by the server."

This indicates that the Automated Device Enrollment (ADE) token needs to be renewed.

Follow the steps in Automated Device Enrollment Integration – Server Token (.p7m) Renewal to renew the Automated Device Enrollment server token.

Once renewed, the error should clear and Automated Device Enrollment will continue to function properly.
