UPnP modem sensors disappeared after I gave HASSIO a static IP :(

Not sure if it is coincidence or not, but my new NBN (Australia) modem got installed yesterday, and HASSIO added all the UPnP sensors for the internet connection automatically. Awesome…
But then I started setting up my network to the new modem and I gave the HASSIO a static IP and port forwarding . Now none of the UPnP modem sensors are working. All the sensors are now “unavailable”.
Any idea how to fix it and get the sensors back?

did you turn off upnp on your router?
