Description

Hello. I am using Kaltura CE 3 on an EC2 image alongside the All in One Video Pack plugin on Wordpress. I cannot use the Standard Editor or play Mix videos. The videos fail to load and the editor thumbnails fail to load. I have tracked down this issue to the fact that, for some reason, Kaltura is cutting off the last letter of the first component of the hostname. For example, my current hostname is:

ec2-x-x-x-74.compute-1.amazonaws.com

However, ONLY on the requests to grab editor thumbnails or video sources, it instead makes requests to:

ec2-x-x-x-7.compute-1.amazonaws.com

Thus rendering editor thumbnails and fully edited video unworkable. Unedited video plays fine from the plugin. I've determined this is not an issue with the Wordpress plugin, as if I hand it the server's IP rather than the hostname then I still see the requests going to the hostname. I am unable to determine if it is a problem with the Kaltura Flash components or the Kaltura CE server itself.

Does anyone know a way to fix this issue?
