Peer listening port closed

[CRMackintosh]

I'm trying to figure out why my peer listening port is always closed.
"Automatically map port" is checked.
My router has UPnP enabled (Netgear RAXE300)
I've saved my debug log after toggling "automatically map port":

Disable UPnP. Then open a specific port and tell Transmission.
