The issue with the connection between mobile phones and computers

[MAKER555]

安卓手机和电脑端不能链接，局域网设置端口为42000，关闭防火墙也都不能链接，可以给出一个安卓手机和电脑链接的教程吗
Android phones and computers cannot be connected, and the LAN port is set to 42000. Even if the firewall is turned off, the connection cannot be made. Can you provide a tutorial on connecting Android phones and computers
