Bug Description

如日志所示，无法联通
两边都能连上FRP服务端，STCP服务端的设置在FRP服务端这里是看得到的，STCP客户端有其他TCP再跑，也跑得动。

server

[NAME]
type = stcp
sk = ***
local_port = 10050

看上去server没有指明local_ip = ？
client中server_name = NAME是标准写法

其实就是127.0.0.1
也尝试过写过，但是问题依旧

我不是提示你 client中server_name = NAME才是标准写法吗？估计你没改，还说问题依旧。
实际上我刚刚把server_name = NAME改成server = NAME以后，跟你报一样错：
custom listener for [] doesn't exist

好吧，是没仔细看文件，这代码是0.37版本抄下来的，但是当年好像就是server_name……是当年脑子烧糊涂了吧……
