🚫 WebRTC Blockers Causing Share Failures
If screen sharing doesn’t start or shows an error during your test or interview, it might be due to browser settings or blocked permissions. Follow the steps below to check and fix the issue.✅ Common Causes and Fixes
| What Might Be Wrong | What You Can Do |
|---|---|
| Browser extensions blocking WebRTC | Disable extensions like ad blockers, VPNs, or privacy tools (e.g., uBlock, Ghostery, DuckDuckGo) temporarily. |
| Site permissions denied for screen sharing | Go to your browser settings and ensure Screen share, Camera, and Microphone permissions are enabled for the site. |
| Using an outdated browser version | Update your browser to the latest version. WebRTC compatibility is best on updated browsers. |
| Browser privacy settings too strict | Reset privacy/security settings to default or allow screen capture for the interview site. |
| Antivirus or firewall interfering with screen sharing | Temporarily disable or whitelist the application/site in your antivirus or firewall settings. |
| Multiple browsers or tabs conflicting | Close any duplicate tabs or other video conferencing tools running in the background. |
| Not using a supported browser | Use Google Chrome, Microsoft Edge or Firefox for best compatibility with WebRTC. |
| Insecure site (HTTP) blocking access | Ensure you are accessing the interview via a secure (HTTPS) URL. |
- Restart your browser and rejoin the session
- Try screen sharing in incognito/private mode to bypass extensions
- Use a different supported browser or device
