Problem with SFTP coconfiguration

[iinfotecnica]

Hello, I did a test with the FTP connection, it worked, but what I need is a connection to a remote server via Sftp, but it's not working.

When I add the information to configuration.php the system crashes.
Does anyone know what could be going wrong?

'Filegator\Services\Storage\Filesystem' => [ 'handler' => '\Filegator\Services\Storage\Filesystem', 'config' => [ 'separator' => '/', 'config' => [], 'adapter' => function () { return new \League\Flysystem\Sftp\SftpAdapter([ 'host' => 'example.com', 'port' => 22, 'username' => 'demo', 'password' => 'password', 'timeout' => 10, ]); }, ], ],

`I added it in the penultimate sequence below

'Filegator\Services\Storage\Filesystem' => [
'handler' => '\Filegator\Services\Storage\Filesystem',
'config' => [
'separator' => '/',
'config' => [],
'adapter' => function () {
return new \League\Flysystem\Adapter\Local(
DIR.'/repository'
);
},
],
],`
