Can't get SSL to work with MassTransit and cloudamqp

Question

I've been struggling to figure out how I'm meant to configure MassTransit and our new dedicated cloudamqp instance to work with SSL (note:everything is working without SSL fine).

I tried adding the UseSsl line in the code below, which I found in some old documentation, but that didn't work:

var bus = Bus.Factory.CreateUsingRabbitMq(sbc =>
          {
              var host = sbc.Host(new Uri(messageBusConfiguration["Host"]), h =>
              {
                   h.Username(messageBusConfiguration["Username"]);
                   h.Password(messageBusConfiguration["Password"]);
                   h.UseSsl(s => {});
               });
            });

In cloudamqp I've set it to allow ampqs too and my services/APIs are setup and running in IIS using HTTPs without any issues.

I suspect I'm missing something fundamental here but I can't find any documentation on it.

This works for me, note that the port must be specified.

var busControl = Bus.Factory.CreateUsingRabbitMq(x =>
{
    var host = x.Host(new Uri("rabbitmq://wombat.rmq.cloudamqp.com:5671/your_vhost/"), h =>
    {
        h.Username("your_username");
        h.Password("your_password");

        h.UseSsl(s =>
        {
            s.Protocol = SslProtocols.Tls12;
        });
    });

    x.ReceiveEndpoint(host, "input_queue", e =>
    {
    });
});

await busControl.StartAsync(new CancellationTokenSource(TimeSpan.FromSeconds(30)).Token);

await busControl.StopAsync();

Side note, I just added automatic port selection for specifying `rabbitmqs` or `amqps` as the scheme on the URI, and automatic selection of SSL. – Chris Patterson Mar 12 '19 at 19:21

That worked perfectly. I'm not sure I completely understand your comment about auto port selection though. Is this going to be in a later release? Does it mean I can just change the URI to be rabbitmqs:/// without the port number? – Ben Thomson Mar 13 '19 at 02:40
Later release will have that but for now you need to specify the port. – Chris Patterson Mar 13 '19 at 04:28

Can I change the "rabbitmq://" scheme to amqp:// and still work? – Harvey Lin Jun 04 '21 at 21:27
Yes, it will work with either `amqp`, or use `amqps` for TLS. – Chris Patterson Jun 05 '21 at 02:26
