1. Allow camera and microphone access
When the browser asks, click Allow. If you clicked Block, open the lock or settings icon in the address bar, set camera and microphone to Allow and refresh the page. Google explains this in its guide to using your camera and microphone in Chrome.
2. Close other apps using the camera
Zoom, Teams, Skype, camera utilities and even other browser tabs can hold the camera. Close them completely, then try again.
3. Refresh the page and restart the browser
Refresh first. If the black screen stays, close and reopen the browser to release the device.
4. Pick the right devices
Click the camera and microphone icons or the browser prompt and choose the correct devices. Laptops with external webcams often default to the wrong one.
5. Check your operating system privacy settings
Windows and macOS have global switches for camera and microphone access. Make sure the browser is allowed in system settings.
6. Update your browser
Old browsers can fail with modern video features. Update Chrome, Edge, Firefox or Safari to the latest version and test again.
7. Disable extensions and VPNs temporarily
Privacy extensions and VPNs can block the camera or slow the connection. Turn them off for a test. If that fixes it, whitelist the site.
8. Test your connection
Use Wi-Fi, move closer to the router and close heavy downloads. If you are on mobile data, switch networks. Low bandwidth causes freezing and delayed video. On phones, see our guide to JerkHub on iPhone and Android.
9. Restart the device
A restart clears stuck drivers and background processes. It sounds basic, but it fixes a surprising number of issues.
| Symptom | Likely fix |
|---|---|
| Black video | Fixes 1, 2, 4 |
| Others cannot hear you | Fixes 1, 4, 5 |
| Video freezes | Fixes 7, 8 |
| Works in one browser, not another | Fix 6 |
