Network Connectivity Requirements: Ports and Domains to Whitelist

Follow

Firewall settings that filter network traffic may be preventing access to certain VHLCentral / Supersite features. In order to ensure the best experience for your students and instructors, your firewall may need to be updated to allow access to the following domains and ports:

  • Allow access to *.vhlcentral.com (all subdomains (.vhlcentral.com).
  • Open ports 80, 443, and 1935 to all TCP traffic (1935 is used for the recording service via RTMP, which is TCP-based)
