title: Why don't I have any Access Control (IAM) in my container?
body: <p>I have no access control (IAM) to a container in my Azure Storage Account.</p>
  
  <p>I have to upload a file to Azure Blob Storage and I always get this error -</p>
  
  <p>"Upload block blob to blob store failed. Details: Make sure blob store SAS uri is valid and permission has not expired. Make sure CORS policy on blob store is set correctly. StatusCode = 0, StatusText = ."</p>
  
  <p>I tried to search about it &amp; I understood that some definitions which related to access control are missing.
  So, I checked what is written in my Access Control tab of the talked container &amp; nothing is viewed there - the tab is empty.</p>
