Description

Occasionally, someone finds my non-public server and attempts to connect. Since they are not whitelisted, the connection fails, but sometimes LuckPerms pre-login processing is performed. On other occasions, such attempts are blocked before LuckPerms sees them. I am not able to ascertain the difference between these cases.

In the former case, an entry is made in LuckPerm's uuidcache.txt. I would prefer that did not occur.

Reproduction Steps

• Login attempt by non-whitelisted player
• Read console/log

Expected Behaviour

Connection attempt should be ignored.

Server Details

Extra Details

It is possible that this is a Paper issue, since the content of whitelist.json is not being honored. If that is the case, I will open a ticket there.

Per comment in PaperMC/Paper#10321, this should be addressed by plugins.

This is not a bug but intended behaviour. Duplicate of #3802
