We recently helped a user who had issues connecting to the server even though we've had 100% uptime in recent weeks. After going back and forth, we narrowed this problem to the use of a filtered DNS resolver (in this case, 1.1.1.3, Cloudflare's "family friendly" DNS). Apparently the word "hacking" in our domain name was triggering this filter, which was likely the case for another user who claimed their ISP had a parental lock interfering with accessing our game.
This update embeds a fallback IP address to hopefully allow users to access the game without having to tinker with DNS or ISP keyword blocks.
