A 403 error in Databricks typically indicates that you don’t have the necessary permissions to access a particular resource or perform an action. This could happen due to various reasons:

Common Causes and Solutions:

1. Incorrect or Insufficient Permissions:
   • Ensure that your user account or service principal has the required permissions to access the Databricks workspace, cluster, or specific resources within the workspace.
   • Contact your Databricks administrator to review and adjust your permissions as needed.
2. IP Access List Restrictions:
   • Check if your Databricks workspace has an IP access list configured. If so, ensure your IP address is included in the allowed list.
   • If you’re accessing Databricks through a VPN or proxy, ensure the traffic is routed through the correct channels.
3. Authentication Issues:
   • If you’re using personal access tokens or API tokens, double-check that they are valid and have not expired.
   • If you’re using Azure Active Directory (AAD) authentication, verify that your AAD account has the necessary permissions in Databricks.
4. Cluster or Workspace Configuration:
   • If the 403 error occurs when accessing a specific cluster, review the cluster’s configuration and permissions.
   • Ensure that the cluster is running and you have the appropriate access rights.
