Hi! If you have a “500 error” then the problem is not in Brave Rewards, but in your Uphold wallet. Please note if you made a mistake when creating the Uphold wallet. I had the same error, it arose because I created two Uphold wallets, one of which was blocked for me, since it is not allowed to have two wallets issued for the same person. The deleted wallet was tied to Brave Rewards Creators, and this caused an error 500. I contacted Uphold support and asked me to restore the deleted, verified wallet. After recovery, I was able to calmly enter Brave Rewards, there is no more 500 error! Sorry, if I wrote something incorrectly, I do not understand English well.
