This brief guide will provide troubleshooting instructions if you experience connection, audio, or video issues, these issues can be linked to your network or firewall configuration. 


Working With Firewalls

Discuss uses cloud technology to maintain a low-barrier, almost zero configuration service across clients.

Sometimes, network firewalls prohibit this traffic.

If you experience connection, audio, or video issues, follow the troubleshooting steps below to clarify and resolve your network configuration.

If you are on a corporate network and the video and audio will not work, it is possible that video traffic is being intentionally blocked by the firewall whilst allowing other TCP (transmission control protocol) traffic over port 443 (HTTPS).  If you believe this is the case, try the following:

  • If your office has a guest network for visitors, try joining that network and accessing the meeting room.

  • If that fails, try accessing the meeting room on your home internet.

If these steps address the issue, then it is likely that Corporate IT will need to whitelist the servers that uses for video and audio.


Turning Off Firewalls

If you are having issues with your camera and microphone being accessed by our platform it may be caused due to a corporate firewall. We recommend users turn off their firewall before joining sessions or reach out to your IT department prior to your project start date.

All users may not have the ability to turn off their corporate firewall.

Windows 10

  1. Go to Settings > Security > Windows Security > Firewall & network protection

  2. Click which firewall to disable

  3. Move the slider to the off position

Mac OS

  1. Go to Apple Menu > System Preferences

  2. Select Security & Privacy > Firewall

  3. If the firewall is on, click Turn Off Firewall


Information For Network Administrators sends all traffic over port 443 via HTTPS.  Our video service will use other ports if they are available for an optimal experience but the service ultimately degrades gracefully to send everything over TCP on 443.

The most common issue experienced by users of our service in corporate environments is firewall software blocking video traffic.  If the website renders but you cannot send and receive video and audio, try the service on an unrestricted network to verify that the user's machine's camera/microphone are not an issue.

If the service works, add rules to whitelist video served via *  We do not provide IP ranges for those servers as they are distributed global

ly for higher quality and are constantly updated and expanded.  

Similarly, specific domains (rather than wildcard domains) cannot be listed because those servers are specified by geographical area and node (eg for server #9 in the San Jose region).

If you're attempting to access Discuss from a restricted network, such as a network with a proxy server, there are some extra considerations you will need to take into account. The decision tree outlined in Tokbox's article about Restricted Networks will help you understand the steps IT administrators need to take in order for the application to work properly.
