Port Forwarding not working

I opend the ports 443 and 80 on the Fritzbox. I enabled UPnP. Still the NCP everytime gives me an error message when I try to activate:

[ nc-forward-ports ] (Sun Mar 19 17:58:46 GMT 2023)

No valid UPNP Internet Gateway Device found.

upnpc : miniupnpc library test client, version 2.2.1.

Go to http://miniupnp.free.fr/ or https://miniupnp.tuxfamily.org/

for more information.

List of UPNP devices found on the network :

I have the same problem. Did you find a solution?

Did you set up a port forwarding? Or should that work with UPnP?

Eventually it worked. I think I had wrong DynDNS information written in my FritzBox. I set up port forwarding plus UPnP.
