Hi folks. Why bitcoind v0.15.0.1 can say "no valid upnp IGDs found" and respectively do not map the 8333 port on a router?
I am certain that the router actually does support UPnP and it does work for other software like skype, utorrent etc. I can even map a port manually via windows explorer. But no luck with bitcoin. It's certainly not the firewall issue, I checked many times that UPnP and SSDP ports are open.
What else it can be?
Thanks for hints in advance.
