Bug Description

端口范围映射内容如下:

{{- range $_, $v := parseNumberRangePair  "7777,8014-8050,8114-8150,8887,8888,9100,9010-9031" "7777,8014-8050,8114-8150,8887,8888,9100,9010-9031" }}
[[proxies]]
name = "{{ $v.First }}-demo"
type = "tcp"
localIP = "192.168.0.122"
localPort = {{ $v.First }}
remotePort = {{ $v.Second }}
{{- end }}

frps重启时，frpc会出现：

send heartbeat to server
send heartbeat to server
send heartbeat to server
send heartbeat to server
heartbeat timeout

只能手动重启frpc，然后就正常连接上了。

配置修改端口少一些，如下：

{{- range $_, $v := parseNumberRangePair  "8014-8050" "8014-8050" }}
[[proxies]]
name = "{{ $v.First }}-demo"
type = "tcp"
localIP = "192.168.0.122"
localPort = {{ $v.First }}
remotePort = {{ $v.Second }}
{{- end }}

重启frps的时候，frpc就能自己重连上。。不确定是不是端口数量太多触发的问题。如果有端口数量限制，请问下是多少。。端口数量多的话，是不是要多用几个frpc，不能放在同一个frpc...
