Azure DataBricks workspace session crashing

Question

Hello Community,

I am working on Azure Databricks. I launch a workspace, and I can work for around 10 mins, and automatically the session crashes and asks for login details.

This is happening multiple times.

Hi @Bhagyesh Doshi
Thank you for sharing the details and the troubleshooting steps you have already tried.

I think your error AADSTS90015 (Requested query string is too long) together with intermittent session logout has been reported by multiple users recently and appears to be related to the authentication flow between Microsoft Entra ID and Azure Databricks.

While the engineering team continues to investigate the root cause, some customers have been able to work around the issue temporarily using the approach below:

Workaround (temporary):

• Create a new user in Microsoft Entra ID
• Assign the required permissions (for example Admin / Owner at subscription level)
• Sign in to Azure Portal using this new account
• Launch the existing Databricks workspace from that account

This has helped reduce the intermittent logout behavior in some environments.

Please note this is only a temporary mitigation and does not replace the underlying fix currently being worked on.

If you try this, kindly share whether it improves the stability in your scenario. Also continue to capture Request ID / Correlation ID if the issue persists, as this helps the service team trace authentication behavior.

Thank you for your patience.
