title: JSchException: Algorithm negotiation fail diffie-hellman-group14-sha1
body: <p>I know this has been asked a few times but I have tried many of the accepted solutions already given. </p>
  
  <p>I am creating a simple SSH tunnel using JSch. and I keep getting this error along with this in the logs:</p>
  
  <pre><code>INFO: diffie-hellman-group14-sha1 is not available.
  </code></pre>
  
  <p>I have already added the Java unlimited policy files to the correct folder and I have added this algorithm to the KexAlgorithms section in the sshd_config file. Below is the full log breakdown.</p>
