Error loading stream: Could not connect to server
I have an embedded player that hosted by JW platform, and it works fine for me. However, one of my clients has a rather enthusiastic firewall.
We've setup a CNAME video.ourdomain.com and they have whitelisted this on the firewall but they still get the error: Error loading stream: Could not connect to server.
They can see the video and the play button but as soon as it would normally play the error appears? Is there an underlying URL that I need them to whitelist or have I setup the CNAME function incorrectly?
Thanks in advance for your help.
