How to handle this error?

[mikmikmik]

I had this error happening once:

PHP Fatal error:  Uncaught RuntimeException: Error reading from socket in /home/.../vendor/phpseclib/phpseclib/phpseclib/Net/SSH2.php:1382
Stack trace:
#0 /home/.../vendor/phpseclib/phpseclib/phpseclib/Net/SSH2.php(2205): phpseclib3\Net\SSH2->connect()
#1 /home/.../vendor/phpseclib/phpseclib/phpseclib/Net/SSH2.php(2184): phpseclib3\Net\SSH2->sublogin('login')
#2 /home/.../someplugin.php(423): phpseclib3\Net\SSH2->login('login', 'pass')
#3 /home/.../class-api.php(161): MyClass->send_file_to_ftp('filename', '<?xml version="...')

Here's the function:

            private function send_file_to_ftp($filename, $xml):bool
            {

                $sftp = new \phpseclib3\Net\SFTP($this->sftp_url, 22);
                if (!$sftp->login($this->sftp_user, $this->sftp_pass)) {
                    exit('Login Failed');
                }
                $sftp->chdir('FOLDER');
                $status = $sftp->put($filename, $xml);
                return $status;

            }

Will the following work to have some log in my admin?

$login = $sftp->login($this->sftp_user, $this->sftp_pass);
if (!$login) {
    return false;
}

I actually had the answer in the Error, it's an Uncaught RuntimeException so I should use a try catch...
It's referenced in the docs

Yah - as it's throwing an exception you'd need to catch it.

That said, if you want to understand why it's not connecting, enabling logging by doing define('NET_SSH2_LOGGING', 2); at the top and echo $ssh->getLog(); after the error would be helpful. Then post the output here and I can take a look.
