Error 501 - PAL_UPNP_SOAP_E_ACTION_FAILED

Couldn't seem to spot a solution on here. Here's the log file from the ConsoleTest app:
network.log

The only change I've made was modifying this line:
var t = nat.DiscoverDeviceAsync(PortMapper.Pmp, cts);
to
var t = nat.DiscoverDeviceAsync(PortMapper.Upnp, cts);

What Open.NAT version are your using? I fixed a similar defect (#28) years ago.

The log says everything works okay until you request the list of open ports and it fails because the router doesn't find the port number 0.

I'm using version 2.1.0.0 according to the reference properties.
