See: https://learn.microsoft.com/zh-cn/aspnet/core/grpc/troubleshoot?view=aspnetcore-8.0#call-insecure-grpc-services-with-net-core-client

在程序启动入口加入如下配置

// This switch must be set before creating the GrpcChannel/HttpClient.
AppContext.SetSwitch(
    "System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true);
