Step-by-Step Configuration Guide

Install GeyserMC Plugin

Download the Geyser-Spigot.jar file and place it in the plugins folder of your Java server. Restart to generate configs. Make sure to select the build version that matches your game server software exactly to prevent class loading errors during startup.

Configure Geyser config

Open 'plugins/Geyser-Spigot/config.yml'. Set the clone port and bind address to allow connections. If you encounter connection issues, double check that your network ports match the allocation numbers shown on the server dashboard.

Install Floodgate Plugin

Download Floodgate-Spigot.jar and upload it to the plugins folder. This allows Bedrock players to connect without owning Java accounts. Make sure to select the build version that matches your game server software exactly to prevent class loading errors during startup.

Connect via Bedrock

Open Minecraft Bedrock, add the server IP and your Geyser UDP port, and log in. This step is critical for proper server operation. Ensure that you have taken a manual file backup before committing these changes to disk.

Recommended Configurations and Setup Files

To configure your server files correctly, navigate to the File Manager in your control panel and open the corresponding configuration files. Paste or modify the settings as shown in the configuration block below. These lines help prevent database thread blockages, optimize tick timing performance, and reduce entity rendering overhead on the game host:

# plugins/Geyser-Spigot/config.yml settings: bedrock: address: 0.0.0.0 port: 19132 clone-remote-port: true remote: address: auto port: 25565

Pro Tip: Ensure the Bedrock port is configured correctly. On shared hosts, you will need to map a custom UDP port in the network allocations tab. Pre-generating world chunks using plugin utilities (like Chunky) is highly recommended for reducing startup lag during exploration.

Frequently Asked Questions

Do Bedrock players need a Java account?

Not if you use Floodgate. Floodgate generates custom UUIDs for Bedrock players, letting them connect with just their Xbox Gamertag.

Can Bedrock players use Java mods?

Only server-side plugins. Custom Java mods (Forge/Fabric) that add new blocks or models cannot be translated by GeyserMC.
