Steps to reproduce

1. 启动FRPS
2. 启动FRPC
3. 出现一堆
   1. start error: custom listener for [xxx] is repeated
   2. [xxx] start error: port already used
      ...

将frps从0.39.1回退到0.37.1, 一切恢复正常

这个bug貌似是0.39引入的问题

No Configurations, no answer.

配置大致如下, 拷贝了部分

运行frpc的 服务器端, 用于提供192.168.1.25的windows remote desktop的服务器端

[SH_USER_AAA]
type = stcp
sk = 12345678
local_ip = 192.168.1.25
local_port = 3389

运行fprc的笔记本客户端, 用于访问服务器端的windows remote desktop 服务
[visitor_SC_USER_AAA]
type = stcp
role = visitor
server_name = SH_USER_AAA
sk = 12345678
bind_addr = 0.0.0.0
bind_port = 9833

---

以前都是正常的, 更换了frps从0.37.1到0.39.1后, 就开始报错了.

替换回0.37.1后, 就又好了, 其他都没变.

好的, 等我明天构建一个例子

[Becods]

[WEB_FFF] start error: port already used
建议使用netstat或者iostat查看端口占用情况

请尽量贴出完整配置文件以及双端日志注意隐藏隐私信息
