title: Set up TLS proxy for Google Cloud Endpoint APIs
body: <p>I have been viewing my Google App Engine endpoint APIs in the API explorer (localhost) without issues, now am getting this:</p>
  
  <p><img src="https://i.stack.imgur.com/RQxSA.png" alt="enter image description here"></p>
  
  <p>in full it says:</p>
  
  <blockquote>
    <p>You are exploring an API that is described or served via HTTP instead of HTTPS. This is insecure and may be blocked by your browser. To fix this, set up a TLS proxy for your API. Alternatively, you can tell your browser to allow active content via HTTP at this site (on Chrome, click the shield in the URL bar), but this will not improve security or dismiss this message.</p>
  </blockquote>
  
  <p>This is one of the API methods I have in my endpoint:</p>
  
  <pre><code>@ApiMethod(
          name = "insert",
          path = "movie",
          httpMethod = ApiMethod.HttpMethod.POST)
  public Movie insert(Movie movie) throws UnauthorizedException {
      ...
  }
  </code></pre>
  
  <p>Since I do not know what's causing this all of a sudden, I do not know what else to show.I've tried updating my browsers (Firefox, Opera, Chrome) with no luck.</p>
