Restart the server to generate the configuration files. Once loaded, stop the server and open the server.properties file. You must set "online-mode" to "false" because the Eaglercraft proxy will handle authentication and data translation. Step 2: Configuring the Eaglercraft Proxy
Ensure your firewall (UFW on Linux or Windows Firewall) has the ports (8080, 25565) open.
Final note: The Eaglercraft project is not affiliated with Mojang or Microsoft. It uses no official Minecraft server code and is purely a reverse-engineered WebSocket proxy for educational and personal use.
