Hi... I have the latest Genie version, the Genie2, with 3 minis. I use the Custom Slot Skill for Mini Genie and utilize the MAC codes on line 12 for the index as well as enter my correct wan_ip on line 8. Everything seems to work fine all the way up to the test step. At the test step, I get the the following result: The remote endpoint could not be called, or the response it returned was invalid. I even tested the pause and hold URL you provided for each of my minis and they do freeze at when I click confirm. My settings are set for allow external devices and I have reviewed everything you have listed under #11. I did have to create a new Lambda, but I'm confident I was able to manage through that correctly. Help!
