RabbitMQ 异常 'None of the specified endpoints were reachable'

Question

我按照有关 RabbitMQ 的教程进行操作，但卡在了创建连接时发生的异常。整个方法如下图：

class Program
{
    static void Main(string[] args)
    {
        var factory = new ConnectionFactory { Uri = new Uri("amqp://guest:guest@localhost:15672/") };
        using var connection = factory.CreateConnection();
        using var channel = connection.CreateModel();
        channel.QueueDeclare("demo-queue",
            durable: true,
            exclusive: false,
            autoDelete: false,
            arguments: null);

        var consumer = new EventingBasicConsumer(channel);
        consumer.Received += (sender, e) =>
        {
            var body = e.Body.ToArray();
            var message = Encoding.UTF8.GetString(body);
            Console.WriteLine(message);
        };
        channel.BasicConsume("demo-queue", true, consumer);
    }
}

这一行：using var connection = factory.CreateConnection(); 我得到这个：

RabbitMQ.Client.Exceptions.BrokerUnreachableException: 'None of the specified endpoints were reachable'

以及三个内部异常：

ExtendedSocketException: No connection could be made because the target machine actively refused it. 127.0.0.1:15672

ConnectFailureException: Connection failed

AggregateException: One or more errors occurred. (Connection failed)

这个异常的原因是什么？ Uri 是否错误或事先设置不正确？ RabbitMQ 似乎运行良好，因为我可以登录 http://localhost:15672/ 并且它已经启动运行.

提前致谢。

编辑：我将 5672 作为 Uri 中的端口，结果是一样的。

关闭防火墙后，它开始工作了。
