title: AWS CLI : Could not connect to the endpoint URL : "https://sts.amazonaws.com/"
body: <p>We have trouble to execute any command on Windows AWS CLI.
  After AWS Configure as follows, almost every command returns the sts access error.</p>
  
  <pre><code>-- AWS Configure
  aws_access_key_id=XXXXXXXX
  anw_secreat_key_id=XXXXXXX
  region=ap-northeast-1
  output = json
  
  -- command &amp; error message
  aws s3 ls
  Could not connect to the endpoint URL : "https://sts.amazonaws.com/"
  </code></pre>
  
  <p>If you went trought the same kind of issue, could you kindly tell me what should be re-configured or added, like any special security group etc. ?</p>
  
  <p>Any advice would be appreciated again.</p>
