frp内网穿透提示 login to server failed: dial tcp xxx.xxx.xx.xx:xxxxx: connectex: A connection

问题描述：frp内网穿透提示

login to server failed: dial tcp xxx.xxx.xx.xx:xxxxx: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

解决思路：

1、FRPS服务监听端口7000被封，换端口试试

2、防火墙映射开放FRPS服务监听端口3400（默认7000）
