title: What does "Reason: DHPublicKey does not comply to algorithm constraints" mean?
body: <p>I saw this error when I wanted to connect to another machine:</p>
  
  <blockquote>
    <p>SEVERE: Could not create connection
    XXXXX: XXXXX Error establishing socket to host and port: XXXXX:XXXXX. Reason: DHPublicKey does not comply to algorithm constraints</p>
  </blockquote>
  
  <p>What is the reason for that?</p>
