Network problem, the network is not easy to open, just change to a better network (not for this reason);
Restart Alipay due to the problems of Alipay software itself;
Due to the problem of health code system, waiting for official repair;
For other possible reasons besides the above reasons, please contact Alipay Health Code Customer Service and wait for customer service to help solve it.
The above is the reason why Alipay health code can't be opened and the solution. If you can't open it, first check whether it is a mobile phone network problem, then clean up Alipay software in the background and reopen it, or empty the memory of the mobile phone, or restart the mobile phone and try to reopen it.
