Model Refresh Errors after June 2026 Gateway Upgrade Resolved Themselves?
Hi Karl-D1,
From what you've described, the gateway installation appears to have completed successfully, other semantic models and paginated reports continued to refresh successfully, and the affected semantic models eventually refreshed without any configuration changes .There is currently no published Microsoft Known Issue that describes intermittent DM_GWPipeline_Gateway_DataSourceAccessError failures following the June 2026 On-premises Data Gateway upgrade.
Since the issue resolved on its own, it appears to have been a transient condition rather than an ongoing gateway configuration issue.I'd recommend monitoring future refreshes to see if the behavior recurs. If it does, please capture the Activity ID, Request ID, Correlation ID (if available), Timestamp (UTC), and the gateway logs, then open a Microsoft Support ticket so the backend diagnostics can be investigated.

Thank you.
Worked fine Friday, and through the weekend. Refresh failed in prod early this morning. I then tried manual refresh in the service and it failed with same errors from last Thursday. I then tried refreshing Dev (totally separate gateway, connections, database, network, etc.) and it is failing again this morning too.
...and now it is working again. I didn't change any settings or touch either of the failing models, and they started refreshing again.
