Sorry for the long topic. I have Mycroft running on RP3, and Home Assistant running on another RP3. I had both working together just fine… until I set up some port forwarding on my router and set up duckdns for external access to my home assistant. It looks like my router allows for NAT loopback (from my pc i ping the duckdns address and it returns my external ip address).
Any suggestions on what might be wrong?
