Homeassistant - Haaska - Alexa Error

HI Everyone,
I have been trying to install haaska to use with Alexa Smart Home voice on homeassistant.
I have followed Dr ZZs video to the T, I have configured Amazon Developer and AWS exactly the same as the video and Haaska tutorial.
When I run test in AWS I get the following error?

        "errorMessage": "404 Client Error: Not Found for url: https://XXXXXX.com/api/alexa/smart_home",
  "      errorType": "HTTPError",
        "stackTrace": [
          "  File \"/var/task/haaska.py\", line 111, in event_handler\n    return ha.post('alexa/smart_home', event, wait=True)\n",
          "  File \"/var/task/haaska.py\", line 66, in post\n    r.raise_for_status()\n",
          "  File \"/var/task/requests/models.py\", line 940, in raise_for_status\n    raise     HTTPError(http_error_msg, response=self)\n"

I confirm that in my conf yaml file I have placed the api as instructed in the documentation and it is green and saved. I have checked the long life token, all the keys in AWS (Client, secret etc) are correct.

I have tested with the port 8123 at end of url and without it. If I have the port then I get a time out error, without the port at the end of the URL I get the above error.

I have tried the following URLs:




I can gain access to homeassistant remotely, so I know it is not that.

Here is the code in the config haaska file on AWS

  "url": "https://xxxx.com",
  "bearer_token": "life long token key is placed here",
  "debug": false,
  "ssl_verify": true,
  "ssl_client": []

Anyone know why I am getting this error and can help?

i followed this video and it work https://www.youtube.com/watch?v=Ww2LI59IQ0A this video is sloower than the video of dr drzzs

Thank You for sharing. It worked, thank you. My only changes from the video you shared was I had to remove the port from Environment variables and also from Account Linking, other than that worked great.
