Sorry if I misunderstood your post, but he would not spawn at every hour and :30 (i.e. 01:30, 02:30, etc.), but instead the field bosses spawn 30 minutes after being killed afaik, feel free to correct me.
That being said, I’ve been channel hopping for the last hour and also haven’t seen him once.
Nope i think thats right. Got to kill him Last Weekend, No Problem
So a little update. He does in fact spawn, but it took significantly longer than it should have. It took around 20 more minutes after I posted my previous message in this sub, so in total around an hour and 15 minutes. And that is just the time I was actually there. Whether this is intended or not, it makes for a rather frustrating experience.
did they fix it ??
No, as I’ve been waiting at his spot for more than an hour now. Super annoying, this isn’t the only boss that has this issue. 
Edit: He spawned after waiting 2 hours.
What time did he spawn do you remember?
Please fix it.
Waited 2 hrs, didn’t see him. @Roxx this has been bugged since release and apparently hasn’t received visibility yet.
Same here fix it please.
Still bugged, please fix it
Im waiting 2 and a half hours by now, switching channels and nothing, its really anoying and a big problem, they have to fix it soon.
Must be bugged for NA/EU servers.
Seems like it’s still bugged. Waited for 1 hour yesterday before I had to go to bed, been standing here waiting for 30 minutes now, think I’m just gonna wait for it to spawn while doing other stuff on 2nd/3rd monitors. I’ll edit it in the time it took for it to spawn if it ever actually spawns.
Edit: Spawned after ~1h30m.
Up , fix this please
Another up, fix the spawn please, only left this for 100 % in shushire
