1. Network connection problem: Please make sure that your mobile phone is in a good network environment and can surf the Internet normally. Please try using the Everbright Bank application in another network environment, or try reconnecting to the network and try again.

2. Data loading: Personal credit preview may need to load a lot of data. If your phone is out of storage space or running memory, the preview may fail. Please check the storage space and running memory of the mobile phone to ensure that there is enough space and resources to supply.

3. Server problem: If the server of China Everbright Bank fails or is under maintenance, the personal credit preview may fail. This is because personal credit information cannot be obtained normally. Please try again later, or contact customer service of China Everbright Bank for help.
