微信小程序里面使用websocket链接nginx服务器，nginx再将请求方向代理到IIS上面的asp.net 网站。websocket链接一直不稳定，经常断开，查看nginx的error.log，发现有如下报错：

21/02/02 10:53:01 [error] 8892#5732: *115154 WSARecv() failed (10054: An existing connection was forcibly closed by the remote host) while proxying upgraded connection, client: 115.60.60.173, server: xjl.*.com, request: "GET /wss?userid=3&gameid=316 HTTP/1.1", upstream: "http://127.0.0.1:8010/wss?userid=3&gameid=316", host: "xjl.ranweitech.com", referrer: "https://servicewechat.com/wxc6228a7ab5ca72d9/2/page-frame.html"

不知道如何修改配置才能解决websocket链接不稳定的问题。
