After doing a bit of research (which included VPNing into India and Thailand) I'm not positive that the hotstar.com listed in SF is the same hotstar.com in Thailand. According to what I read hotstar.com is found in Canada and the UK. It used to be found in the US but was discontinued in favor of Disney+. India and a few other Asian countries (including Thailand) are Disney+ HotStar. StreamFab may not support Disney+ HotStar, you'll have to wait for the staff to come back from their festival. Have you tried just using Disney+? That may not work, too, but it's worth a try.
You didn't answer whether you are a HotStar (actually Disney+ HotStar) subscriber.
