title: Authentication failed: jenkins deployment
body: <p>I´m starting to use jenkins and I have problems with the authentication when I deploy the project. I dont know where to write the credentials. </p>
  
  <pre><code>Authentication failed: The host was not known and was not accepted by the configuration
  </code></pre>
  
  <p>Where could I write my credentials? I dont see that point in the configuration panel. Many thanks!</p>
