Solve Missing profile public key

You get "Chat disabled due to missing profile public key..." when you try to chat?

Paper/Spigot

Set enforce-secure-profile to false in the server.properties file on 1.19+ servers

Velocity

Set force-key-authentication to false in the velocity.toml file (+ try Legacy Forwarding if it fails with modern)

1.16 & older on 1.18+ servers

[00:00:00 WARN]: [ViaBackwards] Custom worlds heights are NOT SUPPORTED for 1.16 players and older and may lead to errors! [00:00:00 WARN]: [ViaBackwards] You have min/max set to -64/384

Those messages sound familar to you?

Then you have 3 options:

Only allow 1.17.x players
Use 1.17 as server version (instead of 1.18)
Use a datapack (thats why you're probably here)
