    Troubleshooting AWSE

    This article discusses solutions to problems faced when using AWSE with Dremio.

    Upgrading to 18.1.0

    Problem: After upgrading to Dremio v18.1.0, when I access a PDS or VDS for my S3 source I receive the error: The preview engine is not online.

    Solution: This issue is caused by a coincidence between a Zookeeper and Dremio port. To resolve this, first restart Zookeeper, and then restart the Dremio service.


    If you continue to see this error with S3 sources, contact Dremio’s Support Team.
