Unable to create uPnP port mapping "failed with code 501 (Action Failed)"

[ferric]

Hi,

I have an 4G Mini Mobile wifi router with uPnP enabled,  s/w Version 4G_WiFi_V01.06.

I'm trying to setup port forwarding for development but am always getting the same error:  

failed with code 501 (Action Failed)

Also, just trying to list any existing mappings that maybe already present on the router I get the error SpecifiedArrayIndexInvalid

I have tried this from a Raspberry Pi and macOS using 3 different clients:

1. upnpc CLI command ( https://github.com/miniupnp/miniupnp ).  v.2.2.4 and v2.2.8
2. portmapper Java GUI (https://sourceforge.net/projects/upnp-portmapper/)
3. upnp router controller GUI (https://snapcraft.io/install/upnp-router-control/raspbian)

The router has an available upnp endpoint but I have to specify a flag to overcome a "not connected?" error, even though I'm using the router right now to post this. Is that error and a blank "ExternalIPAddress" and "Status : Disconnected" underlying causes?

Examples

Getting connection status:

upnpc -i -s

Does anyone have any idea?

Thanks in advance.
