1. Reasons for failure
1. Although it can be directly accessed through the domain name, in the front-end code, the interface does not use the domain name but the IP address

1. Change the IP address in the front-end interface (I personally use axios) to a domain name, and the port remains unchanged.
(Before performing this step, please make sure that the SSL certificate has been deployed and the related configuration of Nginx has been completed)
