我的gRPC-Test项目只在本地主机上工作

Question

我有以下问题。

我创建了一个gRpc服务器(控制台应用程序。我不能在服务器端做Net Core，因为水晶报告:()和一个客户端(WPF应用。Net Core 3.1)而且只要服务器和客户端都在我的机器上(Windows 10)我就可以运行。至于我把我的服务器带到另一台机器(windows Server 2016)，它不再工作了。

这是RPC异常：

Status(StatusCode= "不可用"，Detail= "无法连接到所有地址"，DebugException="Grpc。core . internal . coreerrordetailexception:{ " created ":" @ 1595508082.170000000 "，" description ":"未能选取子通道"，" file ":" T:\ src \ github \ grpc \ workspace _ cs harp _ ext _ windows _ x64 \ src \ core \ ext \ filters \ client _ channel \ client _ channel . cc "，" file_line":3948，" referenced _ errors ":[{ " created ":" @ 1595508082.15

我尝试了所有的变化。以下是我在本地主机上运行的最后一段代码:

服务器:

static void Main(string[] args)
    {
        var cacert = File.ReadAllText(@"root.crt");
        var servercert = File.ReadAllText(@"server.crt");
        var serverkey = File.ReadAllText(@"server.key");
        var keypair = new KeyCertificatePair(servercert, serverkey);
        var sslCredentials = new SslServerCredentials(new List<KeyCertificatePair>() { keypair }, cacert, false);

        // Build a server
        var server = new Server
        {
            Services = { ReportService.BindService(new KKarteReportService()) },
            Ports = { new ServerPort(Host, Port, sslCredentials) }
        };


        // Start server
        server.Start();

        Console.WriteLine("KKarteReport Server listening on port " + Port);
        Console.WriteLine("Press any key to stop the server...");
        Console.ReadKey();

        server.ShutdownAsync().Wait();
    }

客户端

var cacert = File.ReadAllText(@"root.crt");
var clientcert = File.ReadAllText(@"client.crt");
var clientkey = File.ReadAllText(@"client.key");
var ssl = new SslCredentials(cacert, new KeyCertificatePair(clientcert, clientkey));
           
 var options = new List<ChannelOption> { new ChannelOption(ChannelOptions.SslTargetNameOverride, "MyServerHost") }; 
 var channel = new Channel("12.20.18.11", 5001, ssl, options);
 //var channel = new Channel("localhost", 5001, ssl, options);
 //var channel = new Channel(url, ChannelCredentials.Insecure);
 var client = new ReportService.ReportServiceClient(channel);

  using var streamingCall = client.CreateAusschreibung(request);

  await using var ms = new MemoryStream();

  while (await streamingCall.ResponseStream.MoveNext())
  {
        ms.Write(streamingCall.ResponseStream.Current.FileChunk.ToByteArray());
  }

我想念什么？

“主机”变量在服务器端包含什么？问题可能是地址绑定不正确，这会阻止从本地主机（127.0.0.1）以外的IP地址访问服务。尝试在那里输入0.0.0。
