Are you stuck with the frustrating “Get-AzStorageBlob : This request is not authorized to perform this operation” error? Don’t worry, you’re not alone! This error can be a real showstopper, but fear not, dear reader, for we’ve got you covered. In this comprehensive guide, we’ll dive deep into the world of Azure Storage Blobs and explore the reasons behind this error. But more importantly, we’ll provide you with clear, step-by-step instructions to resolve it once and for all.
What is the Get-AzStorageBlob cmdlet?
Before we dive into the solution, let’s take a quick look at what the Get-AzStorageBlob cmdlet does. The Get-AzStorageBlob cmdlet is a PowerShell command used to retrieve a list of blobs from an Azure Storage container. It’s a handy tool for automating tasks, such as data migration, backup, and archiving. However, when you encounter the “This request is not authorized to perform this operation” error, it can bring your workflow to a grinding halt.
Why does the error occur?
So, why does this error occur in the first place? Well, there are a few reasons why you might encounter this issue:
- Insufficient permissions**: The Azure Storage account or container doesn’t have the necessary permissions to perform the action.
- Invalid credentials**: The credentials used to authenticate with Azure Storage are incorrect or have expired.
- Resource not found**: The specified container or blob doesn’t exist or is mistyped.
- Azure Storage Firewall rules**: The Azure Storage Firewall rules are blocking the request.
Resolving the error: Step-by-Step Instructions
Now that we’ve covered the possible reasons behind the error, let’s get down to business and resolve it once and for all. Follow these steps carefully, and you’ll be back to retrieving blobs in no time:
Step 1: Verify Azure Storage Account Credentials
First things first, let’s ensure your Azure Storage account credentials are correct and up-to-date. Follow these steps:
- Log in to the Azure portal (https://portal.azure.com)
- Navigate to the Azure Storage account you’re trying to access
- Click on “Access keys” under the “Security + networking” section
- Verify the account key and connection string are correct and have not expired
Step 2: Check Azure Storage Container Permissions
Next, let’s ensure the Azure Storage container has the necessary permissions:
- Log in to the Azure portal (https://portal.azure.com)
- Navigate to the Azure Storage account and container you’re trying to access
- Click on “Containers” and select the container you’re trying to access
- Click on “Access control (IAM)”
- Verify the necessary permissions are set for the Azure AD user or service principal
You can check the permissions using the Azure CLI command:
az storage container show-permissions --name--account-name --account-key
Step 3: Verify Azure Storage Firewall Rules
If you have Azure Storage Firewall rules configured, they might be blocking the request. Check the rules and ensure they allow access from your IP address or Azure service:
- Log in to the Azure portal (https://portal.azure.com)
- Navigate to the Azure Storage account and container you’re trying to access
- Click on “Firewalls and virtual networks”
- Verify the firewall rules and ensure they allow access from your IP address or Azure service
Step 4: Update PowerShell Credentials
If you’re using PowerShell to run the Get-AzStorageBlob cmdlet, ensure you’ve updated your credentials:
Connect-AzAccount -SubscriptionId
Step 5: Run the Get-AzStorageBlob cmdlet with the Correct Parameters
Finally, let’s run the Get-AzStorageBlob cmdlet with the correct parameters:
Get-AzStorageBlob -Container-Blob -Context (Get-AzStorageContext -StorageAccountName -StorageAccountKey )
| Parameter | Description |
|---|---|
| Container | The name of the Azure Storage container |
| Blob | The name of the blob you’re trying to retrieve |
| Context | The Azure Storage context, including the account name and key |
Common Scenarios and Workarounds
Sometimes, despite following the steps above, you might still encounter the error. Here are some common scenarios and workarounds:
Scenario 1: Using a Service Principal
If you’re using a service principal to authenticate with Azure Storage, ensure you’ve set the correct permissions and credentials:
Get-AzStorageBlob -Container-Blob -Context (Get-AzStorageContext -StorageAccountName -StorageAccountKey -ServicePrincipal -ClientId -ClientSecret )
Scenario 2: Using Azure Active Directory (AAD) Authentication
If you’re using Azure Active Directory (AAD) authentication, ensure you’ve set the correct permissions and credentials:
Get-AzStorageBlob -Container-Blob -Context (Get-AzStorageContext -StorageAccountName -UseConnectedAccount)
Conclusion
And there you have it! With these steps and scenarios, you should be able to resolve the “Get-AzStorageBlob : This request is not authorized to perform this operation” error and get back to retrieving blobs without any issues. Remember to double-check your Azure Storage account credentials, container permissions, and firewall rules to ensure you’re not missing anything.
If you’re still encountering issues, don’t hesitate to reach out to the Azure support team or seek help from the Azure community. Happy blob-ing!

Frequently Asked Question
Having trouble with the “Get-AzStorageBlob: This request is not authorized to perform this operation” error? Don’t worry, we’ve got you covered! Here are some frequently asked questions and answers to help you troubleshoot and resolve the issue.
Q1: What causes the “Get-AzStorageBlob: This request is not authorized to perform this operation” error?
This error occurs when the Azure storage blob is not accessible due to permission issues. This could be because the Azure AD identity or service principal used to authenticate does not have the necessary permissions to read the blob.
Q2: How do I check if I have the necessary permissions to access the Azure storage blob?
You can check the Azure storage blob’s access control list (ACL) to see if your Azure AD identity or service principal has the necessary permissions. You can do this by using the Azure portal or Azure CLI.
Q3: What are the necessary permissions required to access the Azure storage blob?
To access the Azure storage blob, you need to have at least the “Storage Blob Reader” or “Storage Blob Contributor” role assigned to your Azure AD identity or service principal.
Q4: Can I use Azure Managed Identity to access the Azure storage blob?
Yes, you can use Azure Managed Identity to access the Azure storage blob. Azure Managed Identity provides an identity for your Azure resources, such as virtual machines and Azure functions, to authenticate to Azure services, including Azure storage.
Q5: What if I’m still getting the “Get-AzStorageBlob: This request is not authorized to perform this operation” error after checking the permissions and using Azure Managed Identity?
If you’re still getting the error, try checking the Azure storage blob’s firewall settings and ensure that the Azure AD identity or service principal is allowed to access the blob. You can also try using the Azure Storage Explorer tool to troubleshoot the issue.
