UPnP/IGD integration does not take data from the router

Hi,

I’m quite new in Home Assistant world.
I see the UPnP/IGD integration installed in HA and initially properly configured since it recognizes my router in devices ( FG824CD by Sercomm), however the entities KiBs/sent and receive are all the time equal to zero. I’ve been checking the config into the router and it has the upnp protocol enabled, I attach an screenshot with the evidence.

I appreciate your support on this.

Thanks in advance,
Nacho
