UMS Stopped finding renderers suddenly

[zaaack]

Hey there. I'm hoping you can help us figure out what is going on. We were having trouble with UMS (and other DLNA servers) working consistently, but had seemingly fixed it after noticing the wireless connection was set up as Public from when we changed routers. I changed it to Home, and everything worked great for the weekend. The next time we opened it, it wouldn't find any renderers. We've tried a bunch of different troubleshooting steps (forwarded ports, allowed programs in Windows Firewall, forcing the IP of the server), but nothing seems to work. I'm completely stumped. I've attached the logs, hopefully there's something you all know that we don't. Any help is appreciated. Thanks!
