This guide explains how to resolve any potential issues during a meeting with kMeet, the secure, unlimited, and free videoconferencing solution from Infomaniak.

Unable to see or hear the correspondent

If the conference is started, your correspondent has turned on the webcam and their microphone, but you still cannot see/hear them, ask them to check for the presence of a potential firewall on their machine or corporate network.

A firewall may allow solutions like Google Meet or Microsoft Teams without necessarily allowing kMeet streams.

In your firewall settings, here is what you need to allow:

• UDP Protocol: 443.
• For the turn server (recommended), add the TCP port 443.
• Allow the following IP addresses:
  • 185.125.24.0/24 (TCP)
  • 185.125.24.0/24 (UDP)

You can also switch connections (from WiFi to 4G/5G, for example) to check if a firewall is causing the desynchronizations.

Screen sharing impossible

When using the kMeet videoconferencing solution, if the button to share your screen is not available and/or remains grayed out, check the security settings on your computer/operating system regarding…

• … the kMeet application
• … the browser (if you are using kMeet directly online without going through the application):

For example, on macOS, check and then activate the required permissions:

1. Go to System Settings under Privacy and Security then Screen Recording:
   
2. Add your browser if necessary, or even kMeet if you have the desktop app on your computer:
   
3. Then also take note of the icons present in your browser's address bar and detect any potential authorization issues by clicking on the symbols:
