Installed the 3.0.4 version from the GitHub repository setting it up net new with a brand new out of the box dot. I have the bridge setup and devices added with the logging enabled but never see anything in the logs and the dot can't discover any devices. I've quit Plex and one of my other apps that was using 1900 UPnP still no go. What's odd to me is that there isn't anything in the logs at all, almost like the dot isn't attempting to do a discovery but it does find my Nest thermostat with the Nest skill enabled. I don't have any other skills enabled. Looking at the log file I don't see any requests from the dot IP address.
I have reloaded the plugin, reset the echo, waiting 12 hours before trying to discovery, etc. All other alexa functions work fine, just won't discover devices I have assigned in the plugin.
