The 404 error in Databricks typically means the resource you’re trying to access cannot be found. This could be due to several reasons:

Common Causes of Databricks 404 Errors:

• Incorrect URL: Double-check that you’ve entered the correct URL for the notebook, cluster, or other resource you’re trying to access.
