Hello,
Please make sure your Mac and Quest 2 are connected to the same Wi-Fi. Firewall, VPN and anti-virus softwares may block the connection as well, please turn them off when you use AirScreen.
If the connection issue still remains, we hope you can share with us the INFO level logs. Just go to SKYBOX's Global Settings, change the Logging Levels to "INFO", reproduce the issue, then click the BUG icon in the upper-right corner of Global Settings, and send us a bug report attached with logs(tick the "upload logs" box).
After knowing what went wrong, we'll help you solve it as soon as possible.
