The Wireshark captures would be particularly useful. Specifically comparing the working tool does versus what goupnp does.

Great, now I cannot reproduce the issue after a PC reboot.
By the way, device.go
has RequestSCDP()
. Shouldn't this be RequestSCPD()
?

Dang, that's a pain. I was vaguely wondering if it's a lack of IPv6 support in the library.
And yes, looks like that's a typo. I guess I should alias that (but retain old for compatibility). Thanks for spotting it :)

Hmm, not sure if it's an IPv6 problem. Wouldn't that mean that it should never find the devices?
Do you have experience with Wireshark? What should I be looking for? Even though I turned off all services and programs that connect to the Internet, as soon as I start recording, I get lots of entries. I thought UPnP is mostly UDP at least when it comes to discovery, but that SDK I mentioned seems to be doing several TCP requests to my intranet as well.

The IPv6 theory is based on a couple of things: one is that this library hasn't been updated to support IPv6, and the other is pondering if the appearance and disappearance of the problem you experienced was maybe an IPv4 DHCP lease expiring and not being renewed (where IPv6's own auto configuration would probably survive). But the latter being a cause is a complete guess.
I've used Wireshark, although a bit rusty. What might work best is to apply a filter for UDP packets that have port 1900 as either source or destination. That should cut out most of the noise.

Closing as I really cannot reproduce. In case I can, I'll be back with Wireshark dumps. :)

Thanks, and please do :)
