Hello,

I have been successfully using this library for some time now with one cloud vendor, but no matter what I do I can't get it to work with ec2. SSH'ing in terminal with the same private key/user works without problems. I can't figure out how to debug further -- is there a verbose flag to help me understand why this isn't working, or are there any suggestions on how else i can debug this?

Here is my code, for reference.

	Logger::warn('generating new SSH Client');
	$privateKeyPath = __DIR__ . '/../folder/remote_bash_scripts/id_rsa';
	$key = PublicKeyLoader::load(file_get_contents($privateKeyPath), $password=false);
	$ssh = new SSH2($targetHost);
	if (!$ssh->login('root', $key)) {
	    throw new \Exception('Login failed');
	}
