DAPR：目标机器主动拒绝连接（127.0.0.1:3500）

Question

我读过书 https://learn.microsoft.com/en-us/dotnet/architecture/dapr-for-net-developers/getting-started 并构建示例

“多容器 Dapr 应用”。

当我运行自托管模型时，我收到错误：

Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1]
An unhandled exception has occurred while executing the request.
Dapr.Client.InvocationException: An exception occurred while invoking method: 'weatherforecast' on app-id: 'MyBackEnd'
---> System.Net.Http.HttpRequestException: No connection could be made because the target machine actively refused it. (127.0.0.1:3500)

我已重新启动计算机，但错误再次出现。如何修复它？ 我的操作系统：Windows 11
