There are 3 methods (or maybe more) to fix that shitty error:
1: Reboot ur device
2: Switch to current time zones of the game on ur device by go to Setting > Date&Time. If u are playing at Asian server, it should be GMT+9 (Idk for other servers, sorry)
3. If u already bind ur account, try to reinstall the game (well this is the most painful way to fix it)
