My databricks workspace does not stay logged in- it logs out in a minute or so and does not allow me to go back to it when i try Entra log in- it fails 99% of the time.

Answer 1

Hi Amanuel Birri,
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.
