fail complete

when looking at the data stored in the background, it is found that the storage has been successfully obtained

this situation will improve after refreshing the page or restarting the server. However, after a period of time, shows that the payment failed , but the money has been deducted, and the data has been successfully stored at the backend

ask the same question! Did you find the reason again?

ask why most of them call back success, normally and sometimes pay but call back failure, while we do some actions in failure, resulting in inconsistent status errors

from the point of view of the error message, it seems that the network timeout ~ check the ip connectivity, certificate and other information in the error message

found the problem, it is the network is not good. The line was dropped at that time
