Invalid URL and Timeout errors

[aljaxus]

I'm using WSDD on my nas box (running alpine linux). So far I've tested the 0.7.0 and the latest master scripts.

Both error out with the same stacktraces.

The 192.168.1.99 address is an HP printer.

Same issues also present on ArchLinux install of WSDD.

---

The issue occurs as soon as I hit refresh in File explorer>Network on a Win10 box. I assume because Win10 broadcasts a "whois on the network", the printer answers, wsdd receives that response packet, fails to handle it and errors out. These are just assumptions. I have not verified any of it.
