Help to debug "localhost didn’t send any data."

[jonmorrissmith]

Greetings!

Fabulous product... and I've successfully deployed on Azure per the blog post. Thank you for such a clear explanation!

Now trying to build locally.

Having built on OSX/Debian (submitted what I hope are helpful fixes - #39) I'm faced with "localhost didn’t send any data" when accessing e.g http://localhost:8081/departures/bhm

I tested my access token on https://huxley2.azurewebsites.net so I know that's good and have passed it as a parameter to the localhost URL to eliminate any potential configuration issues.

Setting the log level to Information shows a clean start-up and an exec into the container didn't show anything untoward as far as I could see.

Any assistance on how to debug this would be most welcome!

Additional info which may help included below:

Fixed with changes to force Kestrel to listen to any port - added edits into Program.cs (and others) in this fork of Huxley2
