CertBot unauthorized - Invalid response
<p>Am trying to install a certificate for my webapp, which is deployed in my Amazon AWS.</p>

<pre><code> ./certbot-auto certonly --standalone --standalone-supported-challenges http-01 -d www.mywebsite.com --debug
</code></pre>

<p>when I run the above command, I get the following response</p>

<pre><code> The following errors were reported by the server:

   Domain: www.mywebsite.com
   Type:   unauthorized
   Detail: Invalid response from

   report&lt;/title&gt;&lt;style&gt;&lt;!--H1
   {font-family:Tahoma,Arial,sans-serif;color:white;bac"
</code></pre>

<p>Am trying to point to the app which I deployed in <code>Apache tomcat server</code>. I could see the <code>.well-known</code> folder is getting created but the folder is completely empty.</p>

<p>Any Light on this?</p>
