Solution

There was bug in HHVM function idn_to_ascii, it was fixed. You have the following options:

1. Upgrade to most recent version of HHVM (recommended).
2. Set property simpleErrorMessage to true:

use kdn\yii2\validators\DomainValidator;

$validator = new DomainValidator(['enableIDN' => true, 'simpleErrorMessage' => true]);
$validator->validate('-example.com', $error);
echo $error;

Result will be the input value is invalid for all error cases. It is not perfect because doesn't explain the reason to user but correct.
