If you’re using a firewall service (e.g. a corporate or school network) and/or have restricted domains, you may need to whitelist a few ports and domains in order to watch your video.
Viewers should ensure the following ports are open on their network for playback:
TCP/UDP 80 (HTTP)
TCP/UDP 443 (HTTPS)
The following domains should be whitelisted:
cdn.livestream.com
api.new.livestream.com
playback.akamaized.net/*
livestream-f.akamaihd.net/*
secure-playlist.livestream.com/*
*.vhx.tv
*.vimeo.com
*.vimeocdn.com
*.akamaized.net
*.cloudfront.net
