In any day if you are not able to login in your game then, it is nothing to worry. This is a normal issue that you can resolve by using simple steps.
The recommended steps are given below:
1. When logging in, the network is abnormal and try to replace different network environments.
2. Enter the phone's settings - application management - installed to find this game to clear the data, clear the data after restarting the phone and then try to log in (single game is not recommended for this operation, will result in data loss).
3. Uninstall the game reload and try to log in (single game is not recommended for this operation, it will lead to data loss).
4. If it is caused by the maintenance of the game server, it is not possible to log in. It is recommended to replace the other time period and try to log in again.
If the above does not solve your problem, please go to the nearby realme service center for testing.
