RabbitMQ Connection reset Exception

Tags: , ,



I have the same issue from this question: RabbitMQ Connection reset. My code is in kotlin and from https://www.rabbitmq.com/ssl.html#java-client-connecting.

        val connectionFactory = ConnectionFactory()
        connectionFactory.host = "localhost"
        connectionFactory.port = 5671
        connectionFactory.useSslProtocol()

        val connection = connectionFactory.newConnection()
        val channel = connection.createChannel();

        channel.queueDeclare("rabbitmq-java-test", false, true, true, null);
        channel.basicPublish("", "rabbitmq-java-test", null, "Hello, World!".toByteArray())

        val response = channel.basicGet("rabbitmq-java-test", false)
        if (response == null) {
            println("No message retrieved")
        } else {
            val body = response.body
            println(String(body))
        }

        channel.close()
        connection.close()

I have RabbitMQ configured this way:

[
    {rabbit, [
        {loopback_users, []},
        {ssl_listeners, [5671]},
        {ssl_options, [{cacertfile, "pathtorabbitCA.pem"},
                       {certfile, "pathtolocalhost-crt.pem"},
                       {keyfile, "pathtolocalhost-key.pem"},
                       {verify, verify_peer},
                       {fail_if_no_peer_cert, false}]},
        {log, [{file, [{level, debug}]}
      ]
    }
].

I tested this: https://www.rabbitmq.com/troubleshooting-ssl.html#sclient-connection and getting result in cmd:

OpenSSL> s_client -connect localhost:5671 -cert client-certificate.pem -key client-key.pem -CAfile rabbitCA.crt

And exception, it’s coming from line with “val connection = connectionFactory.newConnection()”

2020-05-21 21:13:10,669 [Test worker] WARN  com.rabbitmq.client.TrustEverythingTrustManager - This trust manager trusts every certificate, effectively disabling peer verification. This is convenient for local development but prone to man-in-the-middle attacks. Please see http://www.rabbitmq.com/ssl.html#validating-cerficates to learn more about peer certificate validation.

When I try to check TLS support in Erlang https://www.rabbitmq.com/troubleshooting-ssl.html#verify-tls-support-in-erlang I’m getting this in log:

2020-05-21 21:52:03.031 [error] <0.1530.0> ** Connection attempt from disallowed node 'rabbitmqcli-23412-rabbit@DESKTOP-UI450MM' ** 
2020-05-21 21:52:03.065 [error] <0.1533.0> ** Connection attempt from disallowed node 'rabbitmqcli-23412-rabbit@DESKTOP-UI450MM' ** 

I also tried to configure SSLContext for connectionFactory.useSslProtocol(SSLContext sslContext) method, but output is the same except string about trust manager, just exception. I can’t understand where’s a problem

Answer

Ok, so the answer is quite simple: you need to add a backslash for your path if you using Windows. Path will be {cacertfile, “\path\to\rootCA.pem”}.
