The error AADSTS90015: Requested query string is too long can sometimes occur when accessing the Databricks workspace through older or cached login URLs. This may happen due to authentication redirects or cached session data in the browser.
Please try the following steps:
- Clear your browser cache and cookies, then try signing in again.
- Open the workspace in a private/incognito browser window.
- Make sure you are accessing the workspace using the workspace-specific URL from the Azure Portal rather than a regional URL.
- Go to Azure Portal → Databricks Workspace → Launch Workspace.
- If you have bookmarks saved, update them to the workspace URL shown in the Azure portal.
If the issue continues, please let me know:
- The region of the Databricks workspace
- The time (UTC) when the error occurs
- Whether this happens only for your account or for other users as well
This will help us investigate further.
Hope this helps.
