Avia Server IP wont connect

I have used AviaServer for several years and it Worked great....  Until.....

My PC Update Windows to 24H2 in December. After that I have lost the ability to access the web pages from outside my PC )Laptops, Ipads, Iphones, Fire tablets etc. All inside my network on the same subnet as the PC.

Both with the old version and the 2024 version.

Server returns Connection Refuse 
Things I've tried: I have disabled all firewalls and security, uninstall and reinstall AviaServer, Uninstall and reinstall .Net, configure many variations of firewall rules, and more. Set special routes on my network DNS. (I have my own network and am not relying on a service provider for DNS, NAT, etc.)

I can connect on the PC with \\Localhost or 127.0.0.1

I have many other flight sim apps that do not have this problem. Including direct browser links to FBW and Fenix. and connections through Space Desk.

There is obviously something wrong with the port or internal routing for AviaServer. But I can't seem to figure it out.

Any thoughts?
