上游连接错误或 disconnect/reset 在 headers 之前。重置原因：连接失败 | GRPC 网站 Envoy

Question

我在使用 envoy 代理时遇到此错误：

upstream connect error or disconnect/reset before headers. reset reason: connection failure | 503 服务不可用。

这是我的envoy.yaml

      endpoints:
        - lb_endpoints:
            - endpoint:
                address:
                  socket_address:
                    address: localhost
                    port_value: 3000

我已经删除 http2_protocol_option。它没有用。我的 GRPC 客户端和服务器位于同一网络的不同容器中。我还尝试使用 Go 客户端连接到我的 grpc 服务器并且成功了。

我弄乱了端点地址。我将 localhost 替换为我的容器名称，然后我重建了我的容器，因为文件已通过我的 dockerfile 复制到容器中。
