Ok this is the case
1. If you never play using mod before, you can login and playing with this mod (like my device)
2. After sometime and manual check, developer check new account, they manually sort our account that likely using mod / cheat then banned our device instead
3. If this possible, try to generate or patch the HWID reader, in the backend the API for login always include HWID or device ID, just random generated it will make the game playable again
4. The dev not just ban the account, they ban the phone too
