Use 360 or Hydra to reset the APN, if that doesn't solve the problem, then uninstall the game on your phone again, because some games don't require money, but there will be ads, and Android sometimes you quit the game when you still stay in the phone's memory, occupying data resources, so this is why your phone can be connected after restarting.

Generally, it is very difficult to find out exactly what the cause of this kind of problem is, it is laborious and the effect is not ideal, and the simplest and most reliable way is to back up the data and flash it again.

If other software can be connected to the network normally, it is your YY version problem, see if the network connection is set correctly, if it is correct, you can try to change the version.
