Fix Steps

toolsHow to Fix the Error?

1. Check firewall rules:
   • Ensure the server port (e.g., 25565) is open in the target server’s firewall.
   • Linux example command: ufw allow 25565
   • If using a hosting provider, contact them to verify firewall settings.
2. Confirm it’s a Minecraft server:
   • Verify the IP:port points to a running Minecraft server (e.g., Paper/Spigot).
   • Use ping <IP>:<port> or an online tool to test connectivity.
3. Contact support:
   • If the issue persists, reach out on Discord.
