WebRTC: TCP/UDP network test

If you can't pass the Examus system check before the exam, please take the WebRTC test. If the test fails on TCP or UDP, it means that your TCP/UDP traffic is blocked. 

In this case, we recommend that you do the following:

• Disable your system firewall for the duration of the test.
• Turn off your anti-virus or router firewall for the duration of the test;
• Contact your ISP provider and ask them to unblock the following ports: 
  • TCP: 443 (HTTPS), 3478 (STUN/TURN)
  • UDP: 3478 (STUN/TURN), 49152 - 65535 (WebRTC media)

If there is no possibility to unblock these ports or the problem persists despite the changes – use another Internet connection that is not restricted to TCP/UDP traffic.
