Error starting gRPC call. HttpRequestException: No connection could be made because the target machine actively refused it. (127.0.0.1:6061) SocketException: No connection could be made because the target machine actively refused it.

I am working with gRPC client of c# for work with tinode server using :

var httpHandler = new HttpClientHandler();
    httpHandler.ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAnyServerCertificateValidator;

using var channel = GrpcChannel.ForAddress("http://127.0.0.1:6061/", new GrpcChannelOptions { HttpHandler = httpHandler });

var client = new Lims.Chat.TinodeClient.Console.Plugin.PluginClient(channel);

client.Message(new Lims.Chat.TinodeClient.Console.MessageEvent()
{
    Msg = new Lims.Chat.TinodeClient.Console.ServerData() { },
    Action = Lims.Chat.TinodeClient.Console.Crud.Update
});

but when the action is done these exceptions has been occurred :

: 'Status(StatusCode="Unavailable", Detail="Error starting gRPC call. HttpRequestException: No connection could be made because the target machine actively refused it. (127.0.0.1:6061) SocketException: No connection could be made because the target machine actively refused it.", DebugException="System.Net.Http.HttpRequestException: No connection could be made because the target machine actively refused it. (127.0.0.1:6061)")'

Apparently, the server is listening for gRPC connection on a different port, not 6061. Or, to be precise, there is no listener on port 6061.

Please direct further questions to the forum.
