I can't get Webhooks working. HELP?!

I’m having a bad time trying to get webhooks working. I have typed in an url in the webhooks configuration section like this: http://10.1.0.1:8000/kegbot

the url is actually a simple python web server I have running. I have verified the python server sees posted data by using curl, but each time I pour beer it seems the webhook has not been called. I’m not really sure where to go from here…
