Why can't I sign in to my account?

Here's why that may happen:

1. Your device might not be connected to the network. Check your network settings to make sure you can go online.
2. You might have entered your password incorrectly too many times. In such cases, you can try signing in again in 1 hour.
3. Your actions might have violated our community standards and your account was frozen. You can wait for a while and then try signing in again. If this doesn't help, contact our customer service (400-100-5678).
