Can't get response when send a http post request with /api/alexa

Hi there,

I’m trying to integrate alexa skill to my HA, but after I add alexa: to the end of configuration.yaml, and reboot HA, I try to send a https post request to /api/alexa with body param api_password:mypassword, it’s always return ‘Could not get any response’, i’m using PostMan run this post request.

By the way, I’ve add emulated_hue component in configuration.yaml, and I also can access the http://myhalocalip:8300/api/pi/lights, it will return a json that contains all my components.
And my HA can access it by https, when I type https://myHADomain in safari and chrome, there are a lock icon or green safe tag with it.

does any guys know why /api/alexa can’t access?

Thanks

hi there… is there any one know this problem?
