What is the Cloudflared Tunnel Mod?

The Cloudflared Tunnel Mod is a Minecraft Fabric mod that integrates Cloudflare Tunnel (cloudflared) directly into your Minecraft client. It allows you to create tunnels to connect to Minecraft servers without needing port forwarding or dealing with dynamic IPs.

Where did the idea come from?

This solution was inspired by community discussions on how to use Cloudflare tunnels for gaming:

• Running a Minecraft Server – Reddit discussion on hosting Minecraft servers via Cloudflare Tunnel
• Is it possible to use a tunnel? – Official Cloudflare Community thread exploring technical feasibility
• Hosting through Cloudflare – Community experiences with server hosting

The mod automates all the manual steps discussed in these threads, making the solution accessible to all players.

How It Works

Technical Overview

1. Automatic Initialization: When you launch Minecraft with the mod installed, it automatically:

• Extracts the cloudflared.exe executable from the JAR to the ./data/ folder
• Starts a Cloudflare tunnel using your configuration
• Connects the tunnel to a specific local port

1. Process Management: The mod manages the entire cloudflared process lifecycle:

• Starts the process automatically
• Monitors output and logs
• Stops the process when needed
• Reconnects automatically if the tunnel fails

“cloudflared.exe not found”

• Make sure the file is included in the ./data/ folder
• Check folder permissions

“Failed to start tunnel”

• Check your internet connection
• Ensure there are no firewall blocks
• Try using a different port

“Cannot connect to server”

• Confirm the tunnel is active via logs
• Verify the local port is correct
• Test local connectivity first

Diagnostics

2. Test Connectivity: Ping cloudflare.com
3. Check Processes: Ensure cloudflared is running
4. Test Locally: Try connecting on the local network
