Trouble connecting remotely [Google Wifi & Duckdns]

Hey all, I’ve read some threads and watched videos but no matter what I do I don’t seem to be able to connect remotely.

I was originally behind a double nat (?) that I found out after trying to troubleshoot so I called my ISP and we removed their router and now it plugs into my Google Wifi.

I’ve changed my configuration file to include:

http:
base_url: XXXXX.duckdns.org:8123
ssl_certificate: /ssl/fullchain.pem
ssl_key: /ssl/privkey.pem

My Google Wifi has a static IP address. When I go to forward ports in the Google Wifi app, I select the home assistant and for internal, I put 8123 and external I use 80. I do the same thing to forward 443 to 8123.

When I type in the full address, https://XXXXX.duckdns.org:8123 it just tries to connect but never does. Any ideas or suggestions? Thank you in advance for your time!

Remove those rules and just forward 8123 to 8123.

Doesn’t seem to work. Is there a time that I should be waiting after making changes or is it instantaneous?

I reformatted the card and started over and it’s working now. I left the forwarding as suggested. Thank you for your time.

Just putting this here for my own future referance, as well as others. I had same issue and resolved by the following:

  1. Establishing the Primary Router IP on the modem as the DMZ and entering Port Forwards for the modem assigned Router IP on the modem. In adidtion to the Router assigned IP for HA.
    see here for what I mean: https://www.reddit.com/r/GoogleWiFi/comments/99endy/port_forwarding/

  2. In Google WiFi I established port forwards for 8123->8123 and 8123->443 (G Fi has these ‘backwards’ to most instructions).

  3. In addition to Duckdns I also had to do the Dnsmasq work to overcome Nat loop-back.

This how-to helped most: https://youtu.be/AK5E2T5tWyM once I sorted out the Port forwarding stuff.
