Our Last Hell - Client Validator (Official Companion Mod)

Our Last Hell - Client Validator is a mandatory, highly specialized security utility designed exclusively for the Our Last Hell official Minecraft hardcore server. Built on the Fabric loader for version 1.21.11, its core purpose is to ensure absolute competitive integrity, fair play, and an uncompromised survival experience for all participants.


🛡️ Core Features & Purpose

Unlike traditional content-heavy modifications, this project serves as an administrative and technical bridge between the client and the server architecture. It features a single, highly optimized mechanic:


⚙️ How It Works (Technical Overview)

  1. Handshake Protocol: When you click "Join Server", a secure network handshake is requested.
  2. Modpack Scan: The validator rapidly reviews your active mod list.
  3. Result Evaluation:
    • If compliant: The player seamlessly logs into the world.
    • If non-compliant: The mod halts the connection immediately before the player can spawn or interact with the world, displaying a custom disconnection screen specifying which illegal mod triggered the block (e.g., Freecam).

📌 Installation & Strict Requirements

To connect to the server without issue, ensure your setup meets these exact specifications:


⚠️ Important Notice for Players: Connection attempts made without this companion mod active on your client profile will be rejected automatically by the server's firewall. If you encounter a connection error while having the mod installed, please contact the server administration team via the official support channels.
