Local access with IOS App, Lets Encrypt and DuckDNS

Configuration
1

Hello,
I’m using duckdns with LetsEncrypt.

My Router does not support NAT Loopback / Hairpinning.

Portforwarding 443 -> 8123 is working fine from outside, but from inside my network I cannot connect to HA with the IOS App (Safari is working fine).
The reason for this is because I have to call my local HA IP Adress instead of my duckDns URI, and the LetsEnrypt certificate is only valid for the duckDNS URI, not for my local IP.

Is there any solution for this?

Chrome and Firefox allow you to add a certificate exception (and remember it).

Yes, safari as well. But not the HA iOS App
