🛠️ Login Troubleshooting

Having trouble signing in? The situations below cover the most common login issues reported by players in Bangladesh and explain how to resolve each one quickly.

Forgot Your Password?

Use the "Forgot Password" link on the login screen. Enter your registered mobile number, receive a one-time code via SMS, and set a new password. The whole process takes under two minutes. Make sure your new password is at least 8 characters with a mix of letters and numbers.

Incorrect Credentials Error

Double-check that your mobile number is entered in full (e.g., 01712345678 rather than just 712345678) and that your password does not have an extra space or incorrect capitalisation. If the problem persists after two attempts, use the password reset flow to set a fresh one.

Account Locked After Multiple Attempts

For security, accounts are temporarily locked after several consecutive failed login attempts. Wait 15–30 minutes and try again, or contact the live support team directly who can verify your identity and unlock your account within minutes.

Page Not Loading Properly

Clear your browser cache and cookies, then reload the page. If you are using a VPN or proxy, try disabling it temporarily — some VPN exit nodes can interfere with the login session. Switching between Wi-Fi and your mobile data connection (Grameenphone, Robi, Banglalink, Teletalk) can also help resolve connectivity issues.

SMS Verification Code Not Arriving

Check that your phone signal is stable and your inbox is not full. Wait 60 seconds and request a new code. If the code still does not arrive after two attempts, contact the support team with your registered number and they will assist with manual verification.

Account Not Yet Registered

If you have never created a 399det account, you need to register before you can log in. The registration process takes under two minutes — you will need a valid Bangladesh mobile number and a chosen password. Once registered, your account is ready to use immediately.
