在发送post请求到 negotiate时，ocelot里提示
requestId: 0HM4FAJCPR76R:00000001, previousRequestId: no previous request id, message: Error Code: UnableToCompleteRequestError Message: Error making http request, exception: System.Net.Http.HttpRequestException: Resource temporarily unavailable ---> System.Net.Sockets.SocketException: Resource temporarily unavailable

at Ocelot.Requester.HttpClientHttpRequester.GetResponse(DownstreamContext context) errors found in ResponderMiddleware. Setting error response for request path:/kf/negotiate, request method: POST
整个项目的流程是这样的：
请求->nginx->ocelot->api+signalr
网上g了，stackoverflow也翻了，各种试了，看看有没有大神遇到过同样的问题

先直接connect到api, 在测试ocelot+api, 在测试nginx+ocelot+api, 总归是某个地方的设置有问题.

去掉ocelot是通的
@锋博: 你的这个核心错误是 Resource temporarily unavailable 503 哎, 确定配置没问题哦
@czd890: 嗯，别的资源访问正常
