However this doesn't work properly. The problem seems to be in modules/recaptcha/service.php.
Line 134 is hardcoded to www.google.com:
$endpoint = 'https://www.google.com/recaptcha/api/siteverify';
Manually chaging line to this, fixed our problem:
$endpoint = 'https://www.recaptcha.net/recaptcha/api/siteverify';
But I think a proper solution should be implemented similar to the one in recaptcha.php:
If www.google.com is blocked, the alternative is to use www.recaptcha.net. In the plugin this is documented in: https://contactform7.com/faq-about-recaptcha-v3/#can-I-use-www-recaptcha-net
