I received an automated email with the message: The target [TARGET NAME] has been temporarily disabled due to too many failures. Please check the possible reason of these failures by testing the target first.
When Support and other app experience connectivity issues, some tools still run on the backend, but connection failure occurs.
All targets in Support automatically become deactivated after 21 failed attempts to send. You can easily resolve this by opening Admin Center and navigating to Apps and integrations > Targets > Targets and reactivating the target.
