EventStore.ClientAPI.Exceptions.ConnectionClosedException

EventStore v21.10.8
.NET 7

The code from your tutorial "TCP SDK 5.0.11 (.NET) - Connecting to EventStoreDB - Quick start" doesn't work. I have an error:
EventStore.ClientAPI.Exceptions.ConnectionClosedException: ‘Connection ‘ES-f2cffa2d-a4cc-4850-9976-0113bd272a81’ was closed.’

My code:

using EventStore.ClientAPI;
using System.Text;

var conn = EventStoreConnection.Create(new Uri("tcp://admin:changeit@localhost:1113"));
await conn.ConnectAsync();

var data = Encoding.UTF8.GetBytes("{\"a\":\"2\"}");
var metadata = Encoding.UTF8.GetBytes("{}");
var evt = new EventData(Guid.NewGuid(), "testEvent", true, data, metadata);

await conn.AppendToStreamAsync("test-stream", ExpectedVersion.Any, evt);

var streamEvents = await conn.ReadStreamEventsForwardAsync("test-stream", 0, 1, false);
var returnedEvent = streamEvents.Events[0].Event;

Console.WriteLine(
    "Read event with data: {0}, metadata: {1}",
    Encoding.UTF8.GetString(returnedEvent.Data),
    Encoding.UTF8.GetString(returnedEvent.Metadata)
);

I think your server has TCP protocol disabled. When using v21.10, there's no need to use the legacy client. Move on to gRPC client.
