Getting RabbitMQ connection issues when connecting with SSL

[Makrand Gandhi]

I get the following exception while connecting to a server on port 8071. I was told SSL is configured on port 8071 due to which the connection is blocked but the error message does not explicitly tell anything about SSL handshake failing etc.

I can confirm that 8071 is configured to allow rabbitmq connections.

On debugging further I can see the following method call is failing.

connStart =

                    (AMQP.Connection.Start) connStartBlocker.getReply(handshakeTimeout/2).getMethod();
