I had the same issue finding it! It can get confusing because sometimes international dramas use different titles on different platforms. For a show like 'Teluk Alaska', which I think might be the Malaysian or Indonesian series, your options are a bit limited outside its home region. I looked everywhere when it first aired and ended up subscribing to a VPN service to access the official broadcaster's streaming site, which was TV3's 'tonton' or maybe RCTI+ if I recall correctly. Those are the primary legal sources. The platforms that are common here, like Netflix or Viki, don't seem to have picked it up, at least not in my country. It's a real bummer when geo-blocks make it so hard to watch something legally. I even checked some regional services like WeTV and iQIYI, but no luck there either. The first episode usually sets up the whole coastal family drama, so it's frustrating to not have easy access.
You could also check if the production company sells episodes directly through their own website or a YouTube channel. Sometimes they upload episodes for a fee or even for free with ads, which is still a legal way to watch. I've found a few other series that way. Honestly, the search took me longer than watching the episode itself, but at least I didn't have to resort to any sketchy sites. If all else fails, maybe look into whether any physical DVD sets are available through online retailers, though that's less common now. It's a hidden gem of a show, and I wish more international platforms would recognize that.
