title: Port 443 is close in Google Cloud Instance
body: <p>I am a beginner with Google cloud platform. I have an instance and a custom domain. I installed the certificates for SSL. I am using <a href="https://decoder.link/sslchecker/" rel="nofollow noreferrer">SSL checker</a> and it seems port 443 is closed. I am getting the following error: </p>
  
  <blockquote>
    <p>443 port seems to be filtered, check your firewall/server
    configuration.</p>
  </blockquote>
  
  <p>Following is my configuration for port 443 on firewall:</p>
  
  <pre><code>{
   "allowed": [
  {
    "IPProtocol": "tcp",
    "ports": [
      "443"
    ]
  }
  ],
  "creationTimestamp": "2017-06-27T21:28:24.833-07:00",
  "description": "",

  "sourceRanges": [

  ],
  "targetTags": [

  ]
  }
  </code></pre>
  
  <p>What am I missing?</p>
