Messenger calls not working
Blocked camera or mic, or slow internet
On Messenger in a browser, calls fail when the browser or computer has no permission to use the camera, microphone or speakers. Another app holding the camera, a muted mic or a slow connection also cause it.
How to fix it
Allow camera and microphone access for Messenger in your browser settings.
Close other programs that may be using the camera or microphone.
Make sure your microphone or Bluetooth headset is on and not muted.
Close the browser and restart your computer.
Reconnect to Wi-Fi or switch to another network if the connection is slow.
Ask the other person to try the same steps.
