Start with the checklist below. Most "Iriun not working" reports are actually one of three issues: PC client not running, wrong camera selected in the app, or Windows camera permissions blocked.
Quick checklist
Iriun not working — check these first
- PC client is running — open Iriun Webcam on Windows before the phone app
- Phone app is open and connected — you should see the camera preview on your phone
- Correct camera selected in your app — choose "Iriun Webcam" not your PC webcam
- Camera permissions granted — Windows Settings → Privacy → Camera → allow app access
- Iriun appears in device list — if not, reboot Windows after installation
