Upgrade Sandbox Connector from 1.0 to 1.5

[SkiTheSlicer]

When using Result Options -> Send to connector -> Send to malware analysis sandbox, I get no pop-ups, but the following in '/nsm/elsa/data/elsa/log/web.log' (I'm hand-typing the messages because the server is currently air-gapped):

* DEBUG [2016/07/28 18:29:12] /opt/elsa/web/lib/Controller.pm (2201) Controller::_send_to 55264 [undef]

When using Info -> Plugin -> Send to Sandbox, I receive a pop-up with a title of 'Error' and message of 'Send failed' and get the following in '/nsm/elsa/data/elsa/log/web.log':

I made the following configuration update to /etc/elsa_web.conf and restarted apache2:

{

  "connectors": {
    "sandbox": {
      "site": "192.168.10.24",
      "url": "http://192.168.10.24:8090/tasks/create/file"
    }
  },

}

FYI: I'm currently running off the Security Onion ISO 14.04.4.1, ELSA Rev 1205.
