title: ssh: connect to host gitlab.com port 22: Network is unreachable
body: <p>I'm trying to reach the Gitlab server to clone a repo in a Ubuntu 20.10 computer, but I always get the message:</p>
  <pre><code>ssh: connect to host gitlab.com port 22: Connection timed out
  fatal: Could not read from remote repository.
  
  Please make sure you have the correct access rights
  and the repository exists.
  
  </code></pre>
  <p>So, I've tried to run the command <code>ssh -T git@gitlab.com</code>, but I've got the message:</p>
  <pre><code>ssh: connect to host gitlab.com port 22: Network is unreachable
  </code></pre>
  <p>I've tried in another computer with Ubuntu 20.04 and it worked.</p>
  <p>Anyone can help me with this?</p>
