Consultation on squid proxy server port -- urgent

Squid proxy server port problem help-urgent-Linux Enterprise Application-Linux server application information, the following is a detailed reading. Dear bosses, please help me. I encountered a Problem When configuring a SQUID proxy server in a LAN. When using port 8080, the proxy can access the Internet normally, but when port 808 is used, the SQUID Proxy Server cannot be started, because the proxy port we are using is 808, so the backup server port I configured is also 808, which boss can help me solve the problem? below are some SQUID startup logs I have intercepted;
