DuckDNS setup complete, but can't use IOS app internally anymore

Hi folks,

I’m a new Home Assistant user, and getting a bit lost in the setup steps. I’ve found slightly similar help threads, but nothing has quite cracked it for me yet.

I’ve gone through and setup DuckDNS, and externally I can access everything I need to.

Internally, when I go to https://localip:8123/ I can get in, but I get a warning saying that it’s not secure because (I understand) of the port forwarding rules (local ip doesn’t match duckdns signature details). I can ignore the warning on a browser, but the iOS Home Assistant app doesn’t let me do that.

As a result, I’m a bit stuck internally. I can use the iOS app externally (tether iPad to phone and use cell etc), but I can’t figure out the config from when I’m on wifi at home.

I also understand that DNS forwarding may be an option, but my current router doesn’t seem to support that.

Any kind soul able to help? I’m a programmer by trade, but hardware and networking config are NOT my strong suit.

Have you tried using the duckdns address internally as well?

Yep, just times out unfortunately

So your router doesn’t support dns loopback?

Doesn’t seem to: Radware Page

I also have an Apple Airport Express but it’s not the primary on the network
