Bug Description

Based on the configuration information I provided, start the server (frps) and client (frpc) at the same time, the server log shows normal, check the port "telnet server IP 26000" through the command, the port cannot be accessed normally.
The server passes "netstat -antulp |grep 26000", but there is no port information.
