Hey @ThinkingInCrowd, where are you getting the “unknown host error” message from? Are you trying to access thinkwgpt.fly.dev in your browser?
It sounds like you’re on the right track here, and you’re right, everything you posted about your app status and logs looks fine!
I did notice that thinkwgpt.fly.dev doesn’t resolve to any IP addresses, though (I checked with dig), so I think you might be right about allocating an IP address for your app. fly ips list should tell you whether you have any allocated IPs yet.
