title: websockets.exceptions.ConnectionClosed: WebSocket connection is closed: code = 4008 (private use), reason = Rate limited
body: <p>I am using Discord.py for my bot and this error occurs:
  <code>websockets.exceptions.ConnectionClosed: WebSocket connection is closed: code = 4008 (private use), reason = Rate limited.</code></p>
  
  <p>It happens when I use this:</p>
  
  <pre class="lang-py prettyprint-override"><code>while true:
    activity=discord.Game(name=f"some stuff")
    await client.change_presence(activity=activity, status=status)
  </code></pre>
  
  <p>It is in an async function, so it is not related to async/await usage.</p>
