Hi @Lawro 

To isolate potential network problems, please confirm if you're operating within a Private/Hybrid cloud environment. Besides, I recommend the below troubleshooting steps based on the limited context you have provided.

Quick Check: Attempt to access the Databricks portal directly from the server. Successful access suggests the issue might lie within the api configuration that you are using.

API Testing: Utilize tools like Postman to further investigate by directly interacting with the Databricks API.

Authentication Method: Troubleshooting is generally easier when using a Personal Access Token (PAT) compared to Service Principal authentication with Azure Active Directory (AAD).
