It appears that you are encountering a ResourceNotFound error for blob storage data plane operations despite successful management plane operations and the creation of the storage account. Here are some insights that may help you troubleshoot this issue:

1. Check Container Existence: Ensure that the containers you are trying to access actually exist. The ResourceNotFound error can occur if the specified container or blob does not exist. You can verify this by using the Azure Portal or CLI to list the containers.
2. Propagation Delay: Sometimes, there may be a propagation delay after creating a storage account or containers. Although you mentioned waiting for 10+ minutes, it might be worth waiting a bit longer or retrying the operations after some time.
3. Subscription Policies: There could be subscription-level policies that restrict certain operations. It's advisable to check if there are any policies applied to your Pay-As-You-Go subscription that might limit data plane access.
4. Regional Issues: While it seems unlikely, there could be temporary issues specific to the East US region. You might want to check Azure Service Health for any ongoing issues in that region.
5. Authentication and Permissions: Since you have tested multiple authentication methods and verified that shared key access is enabled, ensure that the permissions associated with the authentication method you are using are sufficient for the operations you are attempting. For example, if using a SAS token, ensure it has the necessary permissions.
6. Diagnostic Logs: Review diagnostic logs for any additional error messages or clues. Azure provides logs that can help identify issues related to authentication and authorization.
7. Contact Support: If the issue persists, consider reaching out to Azure Support for further assistance, especially since you mentioned that operations work in a different subscription.

In summary, verify the existence of the resources, check for any subscription policies, and consider reaching out to support if the problem continues.

Hi @Will,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

As I can see, you are unable to perform the below operations using Azure CLI commands even after creating the Storage Account and container:

az storage container list

az storage blob upload

az storage blob list

Can you please confirm if you are able to access the container and blobs via the Azure Portal? Double-check the configuration settings for the Blob service in the Azure Portal and ensure nothing is misconfigured that could cause an access issue.

Note: Make sure to verify access before running the below commands, and ensure you are logged in to the correct subscription.

Connect-AzAccount

After logging in, verify which subscription you are connected to using the command below, and ensure it matches the subscription where your Storage Account exists:

Get-AzContext

If you face any errors with Azure CLI commands, please try the below Azure PowerShell Commands.

Import-Module Az.Storage

$StorageAccountName = "Test"
$ResourceGroupName  = "venkatrg"
$ContainerName      = "venkat"

$LocalFilePath      = "C:\temp\sample.txt"   # File you want to upload
$BlobName           = "sample.txt"           # Blob name inside container

$Context = (Get-AzStorageAccount -AccountName $StorageAccountName -ResourceGroupName $ResourceGroupName).Context

Write-Host "`n=== 1. List Storage Containers ==="
Get-AzStorageContainer -Context $Context | Select-Object Name

Write-Host "`n=== 2. Upload Blob ==="
Set-AzStorageBlobContent `
    -File $LocalFilePath `
    -Container $ContainerName `
    -Blob $BlobName `
    -Context $Context `
    -Force

Write-Host "`nBlob uploaded successfully!"

Write-Host "`n=== 3. List Blobs in Container ==="
Get-AzStorageBlob `
    -Container $ContainerName `
    -Context $Context | Select-Object Name

Kindly let us know if the above helps or you need further assistance on this issue.
