DuckDNS site not opening

I am trying to access my home assistance outside of my network by using DuckDNS. I have followed the guides to configure it but, it does not seem to work.

I’m using a virgin super hub 3.0 to do the port forwarding and it looks like this:

I have also tried making the Local port range to 443-443 & External port range to 8123-8123 and also done Local port range to 8123-8123& External port range to 8123-8123
And then typed in the URL: https://x.duckdns.org/
