Access to External domain from Internal

[Nekromantik]

Hi all
So I have a web server that has a NAT to forward traffic to it from WAN.
This works fine.
I then had to add that domain and re direct it to Internal IP in Unbound to stop it breaking when Im on the Internal network.
This stopped working after the last update to OPNSense.
Now I started to get OPNSense cert error when accessing from inside as its trying to hit hit the firewall IP on 443 and getting to the firewall instead of going to web server so the unbound dns over ride has broken.
Any tips?
