title: Guacamole Error: The remote desktop server is currently unreachable. If the problem persists, please notify your system administrator
body: <p>I'm installing <a href="https://guacamole.apache.org/" rel="nofollow noreferrer">Apache Guacamole</a> using <a href="https://hub.docker.com/r/oznu/guacamole" rel="nofollow noreferrer">DockerHub's Guacamole container</a> on a macOS Big Sur laptop. From the terminal, I'm running this command:</p>
  <pre><code>docker run \
    -p 8080:8080 \
    -v :/config \
    oznu/guacamole
  </code></pre>
  <p>Then, I'm getting my <code>IP</code>'s address by typing <code>ipconfig getifaddr en0</code> in the terminal. With the <code>IP</code>'s address &amp; port <code>8080</code>, I open my browser &amp; navigate to <code>&lt;ip-address-here&gt;:8080/#/</code> which takes me to the login screen.</p>

  <p>From there, I do the following:</p>
  <ul>
  <li>Enter the Guacamole's default <code>user</code> which it's <code>guacadmin</code> (both <code>username</code> &amp; <code>password</code>).</li>
  <li>Create a new <code>user</code> with <code>admin'</code>s privileges.</li>
  <li>Delete the default <code>user</code> for security reasons.</li>
  </ul>
  <p>Then, I create a new connection with the following parameters:</p>
  <p><strong>EDIT CONNECTION</strong></p>
  <ul>
  <li><code>Name: &lt;connection-name&gt;</code></li>
  <li><code>Location: ROOT</code></li>
  <li><code>Protocol: VNC</code></li>
  </ul>
  <p><strong>Network</strong></p>
  <ul>
  <li><code>Hostname: &lt;ip-address-here&gt;</code></li>
  <li><code>Port: 5900</code> (I think this is the default port for VNC's protocol)</li>
  </ul>
  <p><strong>Authentication</strong></p>
  <ul>
  <li><code>Username: &lt;machine-username-here&gt;</code></li>
  <li><code>Password: &lt;machine-password-here</code></li>
  </ul>
  <p>I hit save &amp; try to connect, but I get to this screen:</p>
