Why is there no port access after changing the apache port?

the artificial customer service system installed by the company uses port 80 of my apache, so if I change my apache port now, my website can only be accessed through XXXX.com:8080 if I use the domain name. Is there any way to hide this port number?
I use thinkPHP + apache2.4 environment configuration

The

port can be omitted unless it is standard, while there are only two 80-> http, 443-> https, in the standard. You can try https,. In addition, you can use different domain names and url under the same port, which can be done through an apache multi-virtual host.
