I agree with most of your comment, but your math is very wrong. 36^12 hashes (lower case alphanumeric) / 126.9 GH/s = 33.7 million seconds, or about 1.18 years. Still way too weak for secure use, but about 16 orders of magnitude above the nanosecond range. How’d you calculate that?
I’ve always just run the server directly from the JAR in a
screen
session. If you’re just running a simple server and don’t need the features of Pterodactyl it’s definitely the easiest option. Just download the JAR from Minecraft’s website to a new directory, and run withjava -Xmx4G -Xms4G -jar minecraft_server.1.21.6.jar nogui
(The page says 1 gig of RAM, but I’d recommend more if you have it available).
