What are the issues?
Does is start and then stop? What are the error messages? What are the problems with re-starting the stream? Was there any issues with the paywall?
My first suspicion would be an ISP issue, due to a foreign services distribution rights in other countries. DAZN's first mistake is trying to distribute this event themselves when, they should syndicate the event with other distributors around the world.
My .02 cents.
I won't go into it much more... I sent Matchroom my damn resume over a year ago!
