SignalR and remote component TCP port

[dtramzter]

I need help. I have a remote component that transmits data to me via TCP through a port (GPS).
in my blazor server app
Program.cs -->
var builder = WebApplication.CreateBuilder(args);
builder.Services.AddSignalR();

var app = builder.Build();
app.MapHub("/current-time");

app.Run("http://*:5000");

MainBub.cs --->
using Microsoft.AspNetCore.SignalR;

public class MainHub : Hub
{
public async IAsyncEnumerable Streaming(CancellationToken cancellationToken)
{
while (true)
{
yield return DateTime.UtcNow ;
await Task.Delay(1000, cancellationToken);
}
}
}
To know if the server was working, create a client and with it it works fine
from client side --->

using Microsoft.AspNetCore.SignalR.Client;

public class MainClient
{
public static async Task ExecuteAsync()
{

var uri = "https://localhost:5000/current-time";

await using var connection = new HubConnectionBuilder().WithUrl(uri).Build();

await connection.StartAsync();

await foreach (var date in connection.StreamAsync("Streaming"))
{
Console.WriteLine(date);
}
}
}

But the remote component (GPS) doesn't connect to the server.

Remote component data (GPS)
Domain: XXX,XX.XXX.XXX
Port: 5000
Protocol: TCP

What am I doing wrong?
