Bash -l / tmp / create_inputs returns connection refused in Rubber> Amazon EC2

After 36 hours of struggling with Amazon EC2, I now stuck to the following.

When Rubber reaches deploy-graylog.rb execution, I get this error:

Here is the log from the last part of the run:

** [out :: production.foo.com.au] graylog-web start/running, process 12772
    command finished in 750ms
    triggering after callbacks for `rubber:graylog:web:bootstrap'

    servers: ["production.foo.com.au"]

    command finished in 725ms

When I SSH to the server and run this one bash -l /tmp/create_inputs, I get the same error

Do I even need Graylog? if not, how can I turn it off?

This is what is in / tmp / create _inputs

function error_exit { exit 99; }; trap error_exit ERR
