Due a lot of botters are in way be ensure to have root to protect you low layer with iptables!


The new update includes:
  • Bedrock users now can bypass the check without needing to have auth-type set to offline. Now it should be floodgate.
  • Now you can choose which players can see the Status ActionBar by giving them the permission nullcordx.stats (old will not work)
  • Actionbar is now toggleable, to avoid re-join.
  • Faster start, cached cloud system
  • Improved overall performance & re-coded most of anti-bot system

How do I disable checks for Geyser users?
It's explained there on some simple steps.

1.) Ensure that Geyser is on the lastest version and Floodgate is installed.
2.) Set auth-type to floodgate or auto on Geyser configuration.
3.) Reset your config and delete your database.db file in order to add new settings to the file and refresh saved players that have passed the check.
4.) Scroll Down the config file, find protection.ingored-ips and geyser.geyser-ips and put the ip of your proxy / machine on both sections.

Do not delete the IP 127.0.0.1 that comes by default on the sections mentioned above, just add your server IP on both.
