.bg tld check is broken

[huglester]

PHP-Whois version: 4.1

PHP version: 8.1

Description
.bg tld check is broken

How to reproduce

$whois = Factory::get()->createWhois();

        // Checking availability
        var_dump($whois->isDomainAvailable("google.bg"));
        var_dump($whois->isDomainAvailable("gofffffogle.bg"));

in both cases we get FALSE

This issue does not exist on my instance. And, it would also be apparent to state that the issue you were having is specific to the whois server (whois.register.bg) and not the php-whois project.
