client 端的日志有更详细的吗？最好是程序开始运行开始的日志。

vhost_http_port = 8080 这个参数确认配置正确吗？
frps 启动日志里有绑定 http service 的日志吗？

我发现 vhost_http_port 不配置，或者配置出错时会有这种情况，已修复。
使用你给的配置，我本地无法复现你的问题，需要确认下是否和我说的情况是一致的。

vhost_http_port = 8080 确认正确，因为我把配置文件copy到老版本里，一切正常。

frps启动时的日志如下：
λ frps
2018/05/21 10:30:30 [I] [service.go:122] frps tcp listen on 0.0.0.0:7000
2018/05/21 10:30:30 [I] [root.go:190] Start frps success

好像没看见绑定 http service 的日志

用你的配置文件启动后日志应该是:

2018/05/21 10:54:28 [I] [service.go:122] frps tcp listen on 0.0.0.0:7000
2018/05/21 10:54:28 [I] [service.go:155] http service listen on 0.0.0.0:8080
2018/05/21 10:54:28 [I] [root.go:190] Start frps success

你的日志看起来就是 vhost_http_port 没有配置正确，确认下文件格式，有没有异常字符之类的。

另外，新版中不再指定 ./frps.ini 为默认配置文件，因为 frps 支持不使用配置文件启动，所以如果需要使用配置文件，需要明确使用 -c ./frps.ini 参数指定。
