[Ask for help] sometimes access timeout when use nginx proxy
i use nginx to proxy my gin service in same server, sometimes it can not access with a time out error from nginx,
nginx log like this:
2022/05/30 09:44:01 [info] 83815#83815: *2609858 epoll_wait() reported that client prematurely closed connection, so upstream connection is closed too while sending request to upstream, client: 47.102.*.*, server: test.example.com, request: "GET /api/example/history HTTP/1.1", upstream: "http://192.168.0.23:8000/api/example/history", host: "test.example.com", referrer: "test.example.com"
but i can access it by curl http://192.168.0.23:8000/api/example/history in the server, and it can fixed by restart gin service
maybe it is not a issue of gin
but this problem is very important and urgent for me, so I want to ask for help
this is my code:
`
func Init() *gin.Engine {
// debug, release, test
mode := "release"
if cfg.Debug {
mode = "debug"
}
gin.SetMode(mode)
r := gin.Default()
// 是否打印访问日志, 在非正式环境都打印
if mode != "release" {
r.Use(gin.Logger())
}
r.GET("/favicon.ico", func(c *gin.Context) {
c.Status(204)
})
//prometheus interfaces
now := time.Now()
startedAt = &now
r.Any("/metrics", func(c *gin.Context) { promhttp.Handler().ServeHTTP(c.Writer, c.Request) })
r.GET("/readiness", readiness)
route(r.Group("/api"))
return r
}
func Run(file string) { r := Init() r.Run(cfg.PortAPI) logx.Info("Server exiting") }
func route(r *gin.RouterGroup) {...} ` thanks
