title: CloudBlobContainer .Exists() will hang/timeout
body: <p>For some reason calling <code>.Exists()</code>, <code>.CreateIfNotExists()</code> and <code>.Create()</code> will hang and never return. I'm not actually getting a timeout exception, I just thought people might search for that term.</p>
  
  <p>Here is the specific code:</p>
  
  <pre><code>var container = _blobClient.GetContainerReference("report_dunderMifflin_details");
  
  container.CreateIfNotExists(BlobContainerPublicAccessType.Off);
  
  //alternatively, because I know it doesn't exist yet
  //I can just call Create and it will hang too
  container.Create();
  </code></pre>
