title: UnexpectedValueException "... is not a zip archive" with composer
body: <p>On AWS server, I have a testing environment and was running well but suddenly it gives me the following error while I tried to deploy the new changes (BTW, in the meantime the WIFI has changed due to HomeOffice)</p>
  
  <pre><code>Unzip with unzip command failed, falling back to ZipArchive class
  Install of mandrill/mandrill failed
  
  [UnexpectedValueException]                                                                                                  
  '/var/www/vhosts/testing4a.example.com/vendor/composer/3e7ad5f270bd79e05aa39b51b8a9cf24.zip' 
  is not a zip archive.  
  </code></pre>
  
  <p>So far tried:</p>
  
  <ol>
  <li>I also tried with another network(WIFI) but still same issue. </li>
  <li>Cleared composer cache</li>
  </ol>
