Regex to exclude URL with special configuration

Question

I want to exclude a url with this configuration https://subdomain.example.com/y22la7hv from a string.

I'm trying to do this with the following regex but is not working: https://subdomain\.example\.com/([a-zA-Z]+([0-9]+[a-zA-Z]+)+)

Where am I failing?

Here it is after lot's of trying and error. Enjoy!

$str = 'https://subdomain.example.com/y22la7hv';
$pattern = '/https:\/\/subdomain\.example\.com\/([a-zA-Z]+([0-9]+[a-zA-Z]+)+)/i';
$exclude_rgx = preg_replace($pattern, '', $str);
