Hello 11-4688,
Greetings! Welcome to Microsoft Q&A Platform.
I understand the issue you’re facing with connecting to your Storage Account (SA) from Azure Data Factory (ADF). Please consider checking the below steps to troubleshoot the issue further.
This request is not authorized to perform this operation - the error message is due to authentication failure when trying to access a resource. Please check the service principal or identity you’re using has the necessary permissions. Specifically, make sure it has the ‘Storage Blob Data Contributor’ role assigned. You can do this in the Azure Portal by going to your Storage Account, selecting “Access Control (IAM),” refer similar thread for reference - https://stackoverflow.com/questions/73388655/status-403-this-request-is-not-authorized-to-perform-this-operation-using-this.
The issue may be your ADF is not in the same Vnet as the storage account. If you enable "enabled from selected virtual networks and IP addresses" and configured firewall (not using Vnet) then you can enable "Allow Azure services on the trusted services list to access this storage account." to access the storage account via ADF. Please see the below blog for more details.
Also please make sure your client's public IP address is allowed. In other words, you need to have the public IP address of the client PC you are using to access the Azure Portal. If you don't you will receive an error.
"Allow Azure services on the trusted services list to access this storage account." works only when you configured the firewall refer - https://techcommunity.microsoft.com/t5/azure-paas-blog/troubleshooting-storage-firewall-issues/ba-p/1944730
Hope this answer helps! Please let us know if you have any further queries. I’m happy to assist you further.
