Description

Thanks for the support of the reCAPTCHA, and i found its config here.

However, here is the problem that some region cannot access google domain google.com(such as China),so the reCAPTCHA cannot be used in these region. Currently I can only disable reCAPTCHA to make the website available for registration.

The official solution is replace www.google.com to www.recaptcha.net (see as recaptcha offical doc can-i-use-recaptcha-globally)

here are the doc

Can I use reCAPTCHA globally?

Yes, please use "www.recaptcha.net" in your code in circumstances when "www.google.com" is not accessible.

First, replace <script src="https://www.google.com/recaptcha/api.js" async defer></script> with <script src="https://www.recaptcha.net/recaptcha/api.js" async defer></script>
After that, apply the same to everywhere else that uses "www.google.com/recaptcha/" on your site.

Possible solution

Maybe a line can be added to the configuration file, such as

;Use www.google.com as default domain
;In some region which cannot access google.com, using www.recaptcha.net to get access
RECAPTCHA_DOMAIN = www.google.com

If u need replace the domain, just change it

;Use www.google.com as default domain
;In some region which cannot access google.com, using www.recaptcha.net to get access
RECAPTCHA_DOMAIN = www.recaptcha.net

It doesn't seem to been completely resolved

This change do fix the question that user cannot acces js files in some region. However, when i try to verify the whole login process, i found the request domain on gitea SERVER still be www.google.com when js file is from www.recaptcha.net . Then i still FAIL to finish the process.

If it's possible, request domain on gitea server can be configured as same as the js file's domain
