Bug Description

frps位于香港阿里云公网环境，frpc位于境内电信内网环境。每次启动frps/c并成功建立连接10-30分钟后就以每5-10分钟一次的间隔断开连接并报告 i/o deadline reached错误，frps的dashboard显示连接离线。每次错误持续约两分钟后重新连接成功，10-30分钟后以此反复。
查阅Issues与CSDN的相同问题提出的解决方案，包括tls加密、改用TCP协议等方式，均无法解决该问题。
运行frpc的服务器存在两套frpc，一个指向位于香港的frps，即存在本问题的frp；另一个指向位于境内公网服务器的另一frps，从未出现过类似问题，两套frps均使用相同版本。

frpc Version

0.46.1

frps Version

0.46.1

System Architecture

frps: linux/amd64，frpc: windows/amd64

Configurations

frps:
[common]
bind_addr = [域名]
bind_port = [端口]
tls_only = true

token = [token]

authentication_timeout = 0

dashboard_port = [port]
dashboard_user = [user]
dashboard_pwd = [pwd]

tcp_keepalive = -1

log_file = ./frps.log

log_level = info
#log max days
log_max_days = 7

frpc:
[common]
server_addr = [域名]
server_port = [端口]

tls_enable = true

token = [token]

protocol = tcp

dial_server_keepalive = -1

[survival]
type = tcp
local_ip = [ip]
local_port = [port]
remote_port = [port]

Logs

在每次重启frps与frpc后，都能成功建立连接：
