Do I need to keep port forwarding with HA Cloud?

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?

No, you don’t need them any more.

Thanks. My router is acting funny and I am contemplating a factory reset. This is one less thing to set up again.
