Error code "Terracotta"

(My English might be not good but i will try to explain the situation)

Whenever i try to sign up in Minecraft it gives me a error with the code "Terracotta". And so i searched up on the web and tried to find a fix including this website but i didnt get any results. The players in this website who also suffered from this error said that their error was fixed randomly at a short time. Its been a week but I still cant log in to Minecraft and play Multiplayer etc.

Can anyone help me about this situation?
