databricks workspace timed out issue

Hi **Trendytech Sumit,
**We are aware that several users are encountering the AADSTS90015 (Requested query string too long) error when attempting to sign in to Azure Databricks.

From the observed behavior—such as intermittent login success, impact across multiple tenants, and session drops—this indicates a service-side authentication issue involving Microsoft Entra ID and the Databricks sign-in flow, rather than a misconfiguration within individual workspaces.

As interim mitigation, you may try the following:

Access the workspace using its direct workspace URL instead of regional links or saved bookmarks

Clear browser cache and cookies, or use an Incognito/Private browsing session

Ensure only one account session is active during sign-in

Test with a different browser to rule out session-related inconsistencies

If the issue persists, collect the Request ID, Correlation ID, and Timestamp from the error page and share them when contacting support. These details will assist the service team in analyzing the backend authentication flow.

We are actively tracking similar occurrences and will provide updates as more information becomes available.

Thank you for your understanding.

Thanks for posting your question in the Microsoft Q&A forum.

It's not normal and is not controlled by STATEMENT_TIMEOUT. This usually indicates an issue with authentication, browser session/cookies, or limitations of a free/trial workspace, rather than a configurable timeout.

To troubleshoot, try a clean browser session, verify if it’s only the UI or also jobs, and test on another device. If it happens in a trial/free environment, there’s typically no way to extend session duration, and moving to a standard workspace is recommended
