We have installed kaltura Community Edition v5.0.0 eagle-10-02 in aws ec2 and running it without any issues for a year. There is a complaint from a specific user from Maldives that he gets a clip not found error in firefox and in chrome he just gets three links video solutions, video platform and video management with white background. I am able to play the vidoes without any issues from India and my other friends also don't have problem from UK as well. Note that i have created a new flavour which i select during upload and not using the default one. I have hosted a sample video for your reference.

Any advice on this will help me trouble shoot the same.
