Web Server Port Forwarding Stopped Working

Hi, I've been running a web server on a local machine using port forwarding. After a recent update / outage (not sure which), the port forwarding stopped working and I can't use my website.

The internet connection itself is completely fine. The local machine is still connected and it still has a reserved IP address in the admin console. The port forwards are still visible in the app. I've tried restarting my router and using the app to "troubleshoot" both the entire internet and the specific device. There are no apparent issues with the setup, but the issue still remains that the web server is not working. 

Does anyone know why my port forwards would stop functioning?
