In this case, the first thing to look at is whether there is a network problem with the mobile phone. This may happen if the speed of the mobile phone is poor or there is no internet access. It is recommended to switch the mobile phone network, or disconnect the network and then reconnect.
If it is not a network problem, you can check whether the real-name authentication information of the user health code is inconsistent with the login account information. If the above two can't solve the problem, it may be a background program problem. I suggest you try again after a while.
