ArcGIS GeoEvent Server: An unrecoverable failure has occurred. Contact your administrator

Error Message

After a machine reboot or upgrade to a later version, attempting to access ArcGIS GeoEvent Server returns the following error message:

Error:
An unrecoverable failure has occurred. Please contact your GeoEvent Server administrator

Cause

This issue may occur after making changes that temporarily shut down ArcGIS GeoEvent Server, causing some back-end services to not start properly. For example, the ArcGIS GeoEvent Gateway service, which is managed by Apache Kafka, may become disconnected.

Solution or Workaround

Restart ArcGIS GeoEvent Windows services

Restart the ArcGIS Server, ArcGIS GeoEvent Gateway, and ArcGIS GeoEvent services in that order, with a five-minute gap between restarting each service. Follow the steps below to do so:

1. On the Windows taskbar, search for and select Task Manager.
2. In the Task Manager window, click Services.
3. Search and select ArcGIS Server. Right-click ArcGIS Server and select Restart.
4. Repeat Step 3 to restart the ArcGIS GeoEvent Gateway and ArcGIS GeoEvent service with a five-minute gap after restarting each service.
