Hello,
Thanks for your feedback.
Please check your firewall settings and allow "airscreen-backend.exe" to communicate through Windows Defender Firewall.
You can also click the "Add Server" option in the upper-right corner of "AirScreen" channel and input the IP address showed on SKYBOX PC Client.

If the above suggestions do not help, please share with us the "Info" level logs. We'd like to check the logs to see what went wrong.
To send logs:
- Click SKYBOX's "Global Settings", change the "Logging Levels" to "Info".
- Reproduce the issue you mentioned, then click the BUG icon in the upper-right corner of Global Settings.
- Send us a bug report attached with logs(tick the "upload logs" box). Thanks!
Best regards,
Lucy
