java - sso cas server不用8443端口访问，改用443默认端口出现404

Question

cas不用8443端口访问，改用443默认端口出现404，下面是我tomcat conf的server.xml配置

<Connector port="443" protocol="org.apache.coyote.http11.Http11Protocol"
           maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
           clientAuth="false" sslProtocol="TLS"
           keystoreFile="C:/Users/Administrator/com.keystore" keystorePass="123456"
     truststoreFile="C:/Program Files/Java/jdk1.8.0_65/jre/lib/security/cacerts"/>
     

当我把port改成443的时候，他还是有提示我就访问不到cas server，而我用8443的时候就可以，然后我就尝试了一下别的端口，7443，发现7443也是可以的，请问是什么问题，是不是cas server哪里的配置url一定要带端口，不能是默认的

补充答案：后来我发现443端口被别的应用占用了，把他进程结束就可以了

Answer 1

Later I found that port 443 was occupied by another application, so I just ended the process
