ssh2 connection to sftp server not working in laravel

I'm trying to connect to a sftp server with ssh2_php extension in a lavarel proyect. The connection work great in a simple php script but the same code doesn't working when i take it to a controller in a blank laravel project.

This is the code of the controller

<?php

namespace App\Http\Controllers;

use Illuminate\Routing\Controller as BaseController;

class Controller extends BaseController
{
    public function test() {

        try {
            $ssh          = ssh2_connect(SFTP_SERVER, 22);
            $login        = ssh2_auth_password($ssh, SFTP_USER, SFTP_PASS);
            $sftp         = ssh2_sftp($ssh);
            $sftp_fd      = intval($sftp);
            $filesystem   = opendir("ssh2.sftp://$sftp_fd/.");
        } catch (\Throwable $e) {
            return $e->getMessage();
        }

     }
}

And here is the error response in postman:

As you can see the catch is not catching the error for some reason.

I'm working with php version 7.2

Any idea?

Thanks in advance

The ssh2_* functions will not throw an exception on failure. Read up on the documentation: https://www.php.net/manual/en/function.ssh2-connect.php (also check out the other functions you are using)

If you want to throw an exception when connection fails, I would do something like this:

$ssh = ssh2_connect(SFTP_SERVER, 22);
if (!$ssh) throw Exception("ssh2_connect failed");
# Do the same for the other functions, check their documentation for return values that designate failure

It might also be the case that everything is working as expected, in which case you aren't sending a response at all, which might explain the ECONNRESET.
