If you are using a network firewall, or any other system to protect your connection, you may need to whitelist the following domains and open these ports to prevent download and playback issues caused by a blocked connection.

Domains: *.mediasilo.com, * .cloudfront.net, s3.amazonaws.com *.shift.io.
Protocols: ftp, ftps, https, rtmp, rtmpt
Ports: 21, 40000-50000 = ftp, 443 = https, 80 = rtmpt, 1935 = ramp

Note: There is no specific IP address to whitelist because our service resolves to various IP addresses.
