Good car e loan can't be opened. What happened?

There is something wrong with the software itself and the equipment.

1. There is something wrong with the software itself: there is a bug when the software goes online, or the software version is too low, so it can only be used normally after upgrading.

2. Equipment problems: the memory of the mobile phone or computer is insufficient, and the network signal is not good. You need to check the network connection of the device, clear the memory and try to open it again.
