If you are connecting to Flow from an Enterprise Network environment, you may have some difficulty signing in or viewing specific content due to heightened firewall security and web traffic monitoring. 

Potential Problems Caused by Restricted Networks

  • Unable to connect to the Dashboard or your webinar environment successfully:
    You could see the following error message:
  • Upon logging in, you only see a blank web page
  • You are unable to see or hear video or audio in the webinar environment

Troubleshooting Steps

For the best experience, please follow these guidelines if you are on an Enterprise/Corporate Network if you experience any connection errors, and contact your IT department and give them the following information:

  • Be sure to run our Flow Speedtest and Connection Checker below to ensure your connection is sufficient for viewing Flow-hosted webinars:


  • Before signing into a Flow Webinar, please disconnect from all VPNs or connections to external networks:
    This will help eliminate problems caused by additional security protocols put in place on these networks that could disrupt communications in Flow.
  • Make sure the domain *.flowapp.com is allowed through your network firewalls and all anti-virus software on your computer and network.
    • Also, ensure that you have the following network ports open in your personal and network firewalls:
      TCP 80
      UDP 80
      UDP 53
  • Disable or re-configure any browser extensions or plugins that may filter browser traffic, such as:
    • Pop-up Blockers
    • Ad Blockers
    • Anti-virus or Anti-malware Plugin
  • Ensure you are on a wired connection, especially when presenting, to allow for the fastest most stable connection to our servers.

If you or your IT department representatives have any questions or problems after following these steps, please contact our Customer Support at support@flowapp.com.
