Messages are not verified on third party “vanilla” server and player reporting is disabled/unavailable.
Steps to reproduce:
Get the latest snapshot server jar from https://www.minecraft.net/en-us/article
Get the Java 25 JDK from OpenJDK
Run in the same folder as the server.jar file this command:
java -Xmx2G -jar server.jarAccept the EULA in eula.txt and repeat step 3
Add yourself to the whitelist with the “whitelist add <targets>” command and login to the server
You should get the warning toast appear in the game (see bellow)
The following toast appears on the screen when joining the server (also see screenshot):
! Chat messages can’t be verified
Messages sent on this server may be modified and might not reflect the original message
Player reporting is also disabled
No modifications are made to the client and server so no warning popups should appear and player reporting should be functional.
This bug only happens on the latest snapshot so this isn’t the official Mojang/Microsoft servers being down as far as I am aware
Environment
Windows 11 (Client or Server), Linux [Bisect Hosting] (Server)
