Hass.io, DuckDNS and FIOS

Has anyone had any luck successfully configuring DuckDNS and Let’s Encrypt using a FIOS Quantum router? I’ve tried multiple port forwarding settings on my FIOS router but have not successfully gotten DuckDNS and Let’s Encrypt to work.

Thanks!

What model?
I have Fios-G1100 and configure port forwarding with no problem.

Same as @Vlad’s experience here. Before moving everything to Ubiquiti gear and ditching their “quantum gateway” I had no problems with port forwarding and Duck DNS.

Thanks for your input. Could you please let me know if this looks correct for the port forwarding:

xxx.xxx.xxx.xxx:8123 Destination Port: 443
TCP Any -> 443

I’ve tried multiple options so I’m not sure what is correct anymore…

Thanks for your help!

I redid the entries in the configuration.yaml file, rebooted, and now everything seems to be working correctly. Thanks for your help!
