I’m assuming, you’re getting ‘Región not Supported’ error. It’s because you’re probably in a region not supported by Brave for Rewards verification at this time. They’re planning to bring unsupported regions back by the end of the year.

Do let me know if you’re facing some other error because I’m not able to understand much of your language and the translator isn’t helping much, I only understood one thing that it said region not supported somewhere.
