What version of frp are you using (./frpc -v or ./frps -v)?
frps -v 0.23.3 and frpc -v0.23.3

What operating system and processor architecture are you using (go env)?
frps - linux and frpc windows 2008 R2

Configures you used:
[common]
server_addr = x.x.x.x (server IP)
server_port = xxx
[web]
type = http
local_port = xxx
custom_domains = my domain

Steps to reproduce the issue:

Describe the results you received:
Connection was interrupted everyday.

Describe the results you expected:
Update the frp thus connection will not be interrupted.

Additional information you deem important (e.g. issue happens only occasionally):
frp was disconnected everyday.

Can you point out what caused this issue (optional)

@aimuch 我用v0.24.1也出现这样的问题，你换成哪个旧版本也出现？用0.1几版本的会不会出现？

底层协议改成KCP，目前可以用了。
补充：
可能跟网络有关系，所在网络防火墙增加了对tcp端口的策略导致。

连接被断开，很大可能是网络环境问题，比如公司防火墙禁止使用 frp 的协议等等。

相同配置，在同一台机器上启动 frpc 和 frps，如果连接没有问题，那么基本上就是上面说的问题。

v0.25.0 版本新增了 TLS 的支持，在 frpc 的 common 中配置 tls_enable = true 来启用，服务端也需要更新到最新版本。

启用 TLS 后，报文特征就不明显了，可能可以避免一些这样的问题。
