Search doesn't find Tablo

I have three devices. Both my laptop and phone (via wifi) find the Tablo. No problem and they have consitently worked great. I can’t get my desktop PC to find the Tablo via the Search/Search Again function in the Tablo app. Since the other two devices find it fine, this leads me to think it could be a firewall issue. My desktop is on the Private (vs Public) zone in Windows 10. I’ve also verified that the Tablo app is in the Windows Firewall and it’s allowed for both Public and Private zones. Is there anything else that could be a factor or something else for me to check? Thanks!

Something to check, some routers have an option to disallow communications between devices on WiFi and Ethernet
