KuCoin Blocked My Transactions and Shows User Forbidden 4112 Error Message

I am experiencing a serious issue with the KuCoin exchange that has left me unable to buy, sell, or withdraw any funds. Every attempt to make a transaction is met with an error message saying "User forbidden 4112." This situation is both confusing and frustrating, as I trusted KuCoin to provide a reliable platform for managing my investments. I have invested my money through this exchange, and it is incredibly disappointing to face such barriers when trying to access and manage my funds. KuCoin was once a trusted platform, but this experience has shaken my confidence in their services. I urge KuCoin to address this issue promptly and restore functionality to my account.
