Original GitHub issue: https://github.com/fatedier/frp/issues/1267
最近发现KCP模式不稳定的情况，前一个月均正常
What version of frp are you using (./frpc -v or ./frps -v)?
0.26.0
What operating system and processor architecture are you using (
go env)?Debian 9, AMD64
Configures you used:
防火墙端口均打开
#frps [common] bind_port = 1234 token = REMOVED vhost_https_port = 443 vhost_http_port = 80 subdomain_host = 242c.cc kcp_bind_port = 9643#FRPC
`
[common]
server_addr = REMOVED
server_port = 1234
token = REMOVED
protocol = kcp
[https]
type = https
local_ip = 127.0.0.1
local_port = 443
use_encryption = false
use_compression = false
proxy_protocol_version = v2
custom_domains = REMOVED
subdomain = www
[http]
type = http
local_ip = 127.0.0.1
local_port = 80
use_encryption = false
use_compression = false
proxy_protocol_version = v2
custom_domains = REMOVED
subdomain = www
`
Describe the results you received:
FRPC日志显示相关错误
2019/05/27 00:53:52 [W] [service.go:130] reconnect to server error: i/o deadline reachedFRPS显示相关错误
[vhost.go:154] http request for host [REMOVED] path [] not foundDescribe the results you expected:
Additional information you deem important (e.g. issue happens only occasionally):
最近出现，远端服务器在日本，客户端在中国
Can you point out what caused this issue (optional)
最新一次测试过程中保持原配置情况下 重启服务器和客户端无法连接。关闭KCP就恢复正常。恢复KCP后连接无法建立
强制结束FRPC后有下列提示：
`

暂时没有定位到原因，需要排查。
@befantasy commented on GitHub (Jun 5, 2019):
感觉和GFW有一定关系.之前偶尔遇到这种情况. VPS换到日本之后尤为频繁, 日本是GFW关注的重灾区. 把协议从KCP改到TCP以后暂时正常. 现在GFW是宁可错杀,绝不放过. SSH这种正常流量都经常被干扰, 会不会是KCP流量无法被GFW识别, 就被归为了可疑流量进行了干扰?
@Milokita commented on GitHub (Jun 5, 2019):
我后来拿另外一个在日本的客户端（208.182.X.X）做测试，连接在同在日本的服务器(45.32.X.X) frpc.ini配置与之前相同，在开启了KCP的情况下依旧报错，可能不是国家防火墙的原因

@woall commented on GitHub (Jun 13, 2019):
23.3版本也是这样的，换tcp后重开进程就好了。
@xqiushi commented on GitHub (Jun 16, 2019):
版本0.27.局网内windows可以正常KCP.而MacOS却报错.而两种OS下TCP没有任何问题.
@Milokita commented on GitHub (Jun 16, 2019):
所以我认为应该是代码的问题
@xqiushi commented on GitHub (Jun 17, 2019):
我重启一下服务器端,结果所有客户端又双叒叕正常了
@asd1614 commented on GitHub (Jul 8, 2019):
我的情况是只要有一个客户端网络被中断后（类似电信宽带光猫重启），所有的客户端都登录不了服务端建立连接
@zbigbird commented on GitHub (Jul 16, 2019):
今天frpc突然出现这个提示，不知道是什么原因？ [W] [service.go:82] login to server failed: i/o deadline reached
有大佬能指点一下吗？
@san3Xian commented on GitHub (Jul 16, 2019):
要不试试在server tcpdump看看？我有个类似情况，server显示收到client报文的，但是frps没有做出反应
@chen23188 commented on GitHub (Jul 17, 2019):
同样的问题，版本0.27，在服务端重启一次frps，frpc就能正常连接了。

重启之后过一会儿还是会掉------------------ 原始邮件 ------------------

同样问题，frps在腾讯云。版本0.27.0
2019/07/24 21:58:55 [W] [service.go:82] login to server failed: i/o deadline reached
感觉是只能存在一个kcp的连接，多个之后会出现这个问题。
@ntkernel commented on GitHub (Nov 23, 2019):
0.29.1重启frps（深圳阿里）后frpc（广州移动）可以连接，关了frpc之后在开一次frpc就出错，在阿里开frpc（深圳）可以运行（frpc的server addr = 公网ip）
当我填错kcp端口时也会出现这个问题
@ntkernel commented on GitHub (Nov 23, 2019):
经测试，广州移动无法kcp连接深圳阿里
美国hostens服务器2.56.175.x可以kcp连接至深圳阿里
估计是网络环境问题，移动封了udp
到时候到学校进行测试
