Wojciech,

Thank you for your reply!  Here are the answers of your questions.

1) Are you using Unity Catalog on your workspace? Yes

2) What is your storage account Firewall configuration setup?

Where can I find the Firewall configuration in my storage account?

3) Which exactly method you are using ? (Do you mount it? Or do you set spark config)?

I tried both mount and set spark config but got the same error.

4) Which authentication method you are using? SAS / KEY / OAUTH ?

I used the access key of the storage account to authenticate.

Thanks again!
