[rabbitmq-discuss] Unable to connect to a node running in Amazon EC2

[murthy at swapstech.com]

Dear RabbitMQ Users,

I have a node installed in Amazon EC2 (in a public domain) and I am able
to telnet and I am also able to see management console from a browser, but
when I try to connect to this server and publish a message, I am getting
the following error. Can you please let me know what is possibly causing
this issue?

Regards
Murthy
