Frequently asked

Does Connection Guard work on Minecraft 1.21?

Yes. 1.21 is the newest Minecraft version Connection Guard declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Which Minecraft versions does Connection Guard support?

Everything the author has declared, from 1.8 up to 1.21. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install Connection Guard on the client or the server?

The server only. Players join with an ordinary Minecraft client and install nothing.

Which server software does Connection Guard need?

Bukkit, Waterfall, Velocity, Spigot, Paper, Folia, BungeeCord. A build for one server platform will not load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for Connection Guard?

Java 21 or newer, because that is what the newest Minecraft release it supports requires. The requirement comes from the game rather than from the plugin itself.

What licence is Connection Guard under?

MIT, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install Connection Guard?

Download the file from the author's own release, drop it into your server's plugins folder, and restart the server. It generates its configuration on first start. Check the Minecraft version matches the one your server runs.

Where do I download Connection Guard safely?

From the author's own page on Modrinth, which is where the data here is synced from. MCReference never mirrors, re-hosts or repackages a file: every download button points at the original source, so you get exactly what the author published.
