How to Fix Zoom Not Working

Most Zoom problems are caused by permissions settings, an outdated app, or a weak internet connection rather than anything complex.

Likely causes

• Camera or microphone permission not granted
• Outdated Zoom app
• Another app using the camera simultaneously
• Weak WiFi connection
• Firewall blocking Zoom
• Audio device not selected correctly

Step-by-step fix

1. 1
   Update Zoom

   Click your profile picture in Zoom → Check for Updates. An outdated app causes most issues.

2. 2
   Check camera and microphone permissions

   Windows: Settings → Privacy → Camera (and Microphone) → make sure Zoom is allowed. Mac: System Settings → Privacy & Security → Camera.

3. 3
   Close other apps using the camera

   Teams, Skype, or even browser tabs can lock the camera. Close all other video apps before opening Zoom.

4. 4
   Test audio and video before a call

   In Zoom settings, click Audio and Video and run the test. Make sure the correct devices are selected in the dropdown menus.

5. 5
   Switch to a wired connection

   If your call keeps freezing, plug your computer into your router with an ethernet cable for a more stable connection.

6. 6
   Allow Zoom through your firewall

   Windows: search "Allow an app through Windows Firewall" and make sure Zoom is ticked for both Private and Public networks.
