title: Confluent Schema Registry - 405 error after creating topic
body: <p>I am running a local version of Confluent (4.0) on MacOS and after starting it up and creating a topic <code>newtopic</code> and going to <code>http://localhost:18081/subjects/newtopic</code> - getting following error:<br>
  <code>{"error_code":405,"message":"HTTP 405 Method Not Allowed"}</code></p>
  
  <p>Going to <code>http://localhost:18081/</code> works fine.</p>
  
  <p>What should I check and how to troubleshoot?</p>
  
  <p>Thanks.</p>
