Hey. This error is caused when you try verifying in a region which isn’t supported for verification as of now. Brave has limited verification to 20 countries as of now, but they’re planning to get workable countries running by the end of this year. They’re working on getting Brazil right now and next is India.
Also the website you provided is showing you countries which are supported to view ads for brave rewards and that has nothing to do with verification. You can still participate in Brave Rewards and keep earning BATs and claim them each month. They’ll be stored on local files so do make sure you don’t reset or reinstall Brave so as to Keep your BATs on your device.
The link below will show you countries supported for Brave rewards verification →

Today’s update via Community Call didn’t say much, just that they are working to get Brazil and India going ASAP. Hoping to get other countries back quick too. When asked about whether regions should be supported by the end of the year, they said most should definitely be added before then. While that’s still not saying much, at least we now have an end game in mind, which will be hoping everyone is back up and running in the next few months. Some won’t be, but that’s just how life works. So le…
Hope this helps. Cheers!
