For the past year I had been connecting to Home Assistant using DuckDNS.
I had too many connection problems with DuckDns that I subscribed to the Home Assistant cloud. It was easy, painless (compared to DuckDNS), and it works. (Besides supporting NabuCasa).
When using DuckDNS, I had forwarded ports 443 and 8123 in my router. Do I need to forward them any longer since I am not using DuckDns?
