Once you have set up Geyser on your server, you're ready to join from the bedrock editions. Make sure that if you plan on joining from consoles or mobile devices, you also have Floodgate installed which allows players to join your server even if they do not own the Java Edition of Minecraft. Here's how you can join your server from Bedrock Edition.
1. From the main menu, click Play
2. Open the Servers tab and click Add Server
3. Enter your server's IP and Geyser port. You can now connect to your Java server from Minecraft for Windows, iOS, Android, and Consoles.
