WebRTC Test - Audio and Video Streaming Check

Before you join a webinar on Flow, it is better to verify that you can hear audio and view visuals without any problems. This test checks whether your internet connection/local network/computer can receive audio and video streaming.

We recommend turning off your VPN connection to prevent issues with audio/video during the webinar.

Please run this test to check the readiness before the webinar as this is a critical proactive step to ensure you receive an uninterrupted stream of audio and video.

1. Click here to open the testing tool
2. Click the Start Flow Capability Test to start the test

1. Re-run the test using the same browser. If it fails, use a different browser and test it. Note down the information from the tool providers you
2. Use a different internet connection if possible - you could use your mobile device and Flow's mobile version.

If none of these is possible/not working, go to the step below

1. Go to the following link and run the test: https://test.webrtc.org/ and collect the test results (screenshots)
2. If you are accessing the webinar through your own internet connection (i.e. home internet), contact a Flow support agent by sending a live chat (at the bottom left on this page). Don't forget to send us the information collected earlier.
3. Enterprise Network Users: If you are accessing the webinar through a work network, a government facility, or any other corporate network where connections are often filtered, read this guide and forward it along with the information collected to support representatives of your IT Department.

1. Browser extensions that block WebRTC: 
   • WebRTC blockers such as browser extensions must be disabled such as "WebRTC Control", "WebRTC LeakSheild", etc.
   • In Firefox, go to"about:config" and in the search box, search for "media.peerconnection.enabled". This must be set to true. If it is set to false, double click to enable it
2. WS/WSS Protocols: Check if these protocols are not blocked in your router/local network (mainly, ports 443 and 80 outbound)
   
3. If STUN/TURN protocols are not blocked in your router
   
4. If UDP Ports are not restricted (outgoing) in your router
5. If ports such as 53 are not blocked (outgoing).

• Download: This is your download speed, in Megabits per second (Mbps), and represents how fast you can download files and data.
  • The higher this number, the more data your connection can handle FROM our servers
  • The Flow requires at least a 2 Mbps download speed
  • We recommend 5-10 Mbps for an optimal experience.
• Status
  • Good: Connection matches the requirements
  • Average: Connection can hold (while prone to certain disruptions)
  • Bad: Not matching the requirements

• Verify you are on the fastest, most stable network available:
  • This often means being on a wired connection instead of wireless.
  • While the speed of modern wireless networks is usually fine, sometimes they are not the most stable, due to many possibilities for signal interference which can be disruptive for a live webinar
• Check for any software that may be filtering traffic from Flow servers:
  • These can be things like anti-virus or anti-malware applications, ad-blocking plugins in your browser, or restrictions put on your computer or network by your Internet Service Provider (ISP) or IT Department (for corporate users)
• Ensure you have the following network ports open in your personal and network firewalls (you may need help from your ISP or IT department to do this):
  • TCP 80
  • UDP 80
  • UDP 53
