Lots of posts on this, all are wrong. Both methods (manual modification of outputs.conf files and installing the app from the cloud management interface) fail with the same old errors that everyone else complains about.

I have linux and OSX hosts on the same network and others are hitting the sandbox correctly.
I can TELNET to the input- :9997 address.
Please help. I am really over this. I have used every link mentioned in the other posts and none work. Well, except for the command line testing on the server side, but given I am using the cloud sandbox, I do not have CLI access.
