Any 💡's why?

I'm trying to redeem my points for rewards for the 100th time, just kidding I don't know how many times but I've redeemed numerous times. But all of a sudden I want to redeem again and I have over 4,200 points but it's showing me unexpected error (code 212) 

Anyone out there have an idea (💡) why this is happening and I've tried to reach out through email but still no response.
