Failed to connect to your database server
Change the settings in your settings.php file.
For remote server you should change this like below;

$databases = array (
  'default' =&gt; array(
    'default' =&gt; array (
      'database' =&gt; 'name of database uploaded on remote server',
      'username' =&gt; 'root',
      'password' =&gt; 'root',
      'host' =&gt; 'localhost',
      'port' =&gt; '',
      'driver' =&gt; 'mysql',
      'prefix' =&gt; '',
    ),
  ),
);



'username' and 'password' are for the remote server
'host' is the hostname of the hosting server
