Azure Databricks session keep expiring in 5-6 mins and after 3-4 login and error screen appears

Hi **Devashish Sil,
**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.

The behavior described (very frequent session expiry in Azure Databricks followed by repeated redirects and the AADSTS90015 error) is not covered in the provided documentation. The context only includes guidance for:

• General Databricks connectivity and compute issues
• OAuth M2M authentication troubleshooting
• Kafka connection issues
• Azure portal sign‑in and subscription/tenant problems (including blocked or inactive tenants)

None of these address short interactive session lifetimes or the specific AADSTS90015 “Requested query string is too long” error when signing in to Azure Databricks.

Because of this, the only supported next step based on the context is to open a support request so that the tenant and workspace configuration, Entra ID sign‑in logs, and Databricks logs can be reviewed by support.
