Discord.com Gives "Failed To Make Purchase" Error When I Try to Buy Nitro

I accidentally bought Nitro basic and I want to increase my nitro, but when I choose monthly, it gives an error. There is no problem with other (+4 reinforced v. S) nitros, but when I try to buy the 75 TL monthly, "No way! The purchase could not be made. Please open the application again and try again." gives a warning. Since I bought Nitro Basic with Google Play, I cannot upgrade Nitro from the computer, it does not support it. I even wrote to Discord support, the conversation continued for a long time, but I still haven't received a response yet.
