Google Recaptcha and network domain

I am trying to use google Recaptcha with a network domain, "corpvm", but when i configure the domain and ensure that the API keys(site, secret) are correct, it still doesnt work.

Everything work fine on localhost, obviously, but when i try to hit the host http://corpvm , the captcha component say "ERROR: Invalid domain for site key".

Am i doing something wrong? Is writing "corpvm" in the domains section of Key Settings is enough?

Thanks in advance!
