NginxProxyManager can not reverse proxy its own Web page port?

[yggcwx]

Excuse me:When I configure the domain name for the web port where NginxProxyManager itself resides on the management page, the configuration is successful and the status is displayed normally. However, the reverse proxy is invalid and cannot be accessed by domain name. You can only access web pages by adding ports, which is the same as the IP address. How to solve this problem?

请问：NginxProxyManager不能反向代理自身web页面所在的端口吗？当我在管理页，给NginxProxyManager自身所在的web端口配置域名时，可以配置成功，状态显示正常。但实际上反向代理无效，通过域名无法访问，只能和ip一样，通过加端口的方式访问web页。怎么解决这个问题呢？
