Hi @rilagan
Have you made sure to click “allow” on a prompt that says “spacedesk would like to find and connect devices…” right after you installed it?
aside from that, please check the following:
1. Check your WiFi router settings if it has client isolation enabled.
(This setting prevents direct communication between connected devices/computers.)
2. Do you have VPN (Virtual Private Network) active? If yes, please disable it.
3. Are you using any third party antivirus/firewall? if yes, Please add spacedesk in the exception list or ‘Allow List’
4. Check on your iOS Viewer Settings -> Privacy -> Local Network, if spacedesk is on the list and enabled?
5. Is your primary machine and iPad device connected to the same local area network?
6. On your primary machine, please try to set your current Network Profile to “Private” via Windows Settings -> Network & Internet -> Properties.
