Remote access setup fine but lost local access

Configuration
1

I finished following this tutorial https://www.youtube.com/watch?v=BIvQ8x_iTNE by Bruh.
I have the external port 443 forwarded to 8123 internal port.
External access is fine but I noticed I can no longer access the IP address internally. eg 192.168.1.100:8123
Is this a normal part of the process and I am meant to use the external access only or should they both work?
If so how do I get internal access back?

both should work
are you using https://INTERNALIPOFHASS:8123 ? ensure its https otherwise it wont work.

that did the trick I was missing the https:// thanks for your help.
I did notice google isn’t a fan of it and says it’s unsecure and when clicking on more details i get “This page is insecure (broken HTTPS).”

Is that normal or have I set something up wrong?

I used the tutorials using my duckdns:
ssl_certificate: ‘/etc/letsencrypt/live/yourdomain.duckdns.org/fullchain.pem’
ssl_key: ‘/etc/letsencrypt/live/yourdomain.duckdns.org/privkey.pem’

Is there somewhere in HA i can go to confirm the cert and key?

The certificate knows only of the FQDN, but infact, you now access a https site via a IP address, so the certificate isnt signed for a 192.168.X.X domain.
Its fine to create an exception.
If you have an internal DNS server, you can setup a A record. Most people dont have this available on a home network though.

thanks for the quick reply, I don’t believe I have an internal DNS server, will leave it as is for the moment if there’s no harm. thanks again.

Your router may be providing internal DNS, worth checking. Also, if you are running Windows, you could manually edit your hosts file.
