I bought a subscription to ISY portal, but only realized a couple of months ago that I wasn't able to access the ISY outside the house. It only works on my home wifi, which is... not the point of ISY portal... so today I sat down to debug it. I turned off the wifi on my phone and opened UD Portal, and got the error.
Everything I've looked at seems right as far as I can tell. I've taken screenshots of all the configuration screens and the error I'm getting. Any ideas what's going on? Did I miss something? I'm decently proficient with my home networking setup (I ran ethernet to multiple rooms, have switches, a NAS, but I'm not a networking expert per-se...but ISY portal shouldn't require me to be one, right?).
