Alexa integration

I am starting to experiment with Alexa and Home assistant integration. Currently I am using the hue emulator to turn things on and off with great success. I wanted to get some custom commands working so I tried to follow some of the instructions out here. I setup a location intent in alexa and have the following checks in the testing dashboard.

I can access HA remotely from my phone with wifi turned off.

I am getting the following error in the Alexa simulator when I try to test my intent.

my password is correct and is all printable ascii characters between A-Z and a-z. No numbers, special characters or anything else.

Any thoughts would be appreciated.
