Dataflow refresh error

Hi Janee 

Thanks for using the Microsoft Fabric Community.

The error message is generic, making it difficult to determine the exact cause. Since the manual refresh was successful, the issue is likely due to temporary connectivity issues, as mentioned by Akash_Varuna.

Refresh failures can also occur due to expired credentials. Try clearing your browser cache and re-authenticating.

Additionally, there are certain refresh limitations for Dataflows that you may want to review: Dataflow Gen2 refresh - Microsoft Fabric | Microsoft Learn.

If the issue persists, please raise a support ticket :Microsoft Fabric Support and Status | Microsoft Fabric and share the Request ID and Activity ID for further investigation.

Hope this gets resolved soon! Feel free to reach out for further assistance.
