  <p>And this is what appears to me on the <strong>jupyter</strong> notebook when I try to run something on the <strong>python3</strong></p>
  
  <pre><code>Connection failed
  A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration.
  </code></pre>
  
  <p>I created the <code>SSL</code> this way:</p>
  
  <pre><code>openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout mykey.key -out mycert.pem -sha256
  </code></pre>
  
  <p>How can I fix this mistake?</p>
  
  <p>My PC is a MAC, in AWS I have installed a Linux.<br>
  I am using Google Chrome Version 80.0.3987.163</p>
