Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

Mod loader

Minecraft version

⬇ Download for 26.1–26.2 · NeoForge⬇ Download for 1.21.9–1.21.11 · NeoForge⬇ Download for 1.21.1–1.21.8 · NeoForge⬇ Download for 26.1–26.2 · Fabric⬇ Download for 1.21.1–1.21.11 · Fabric⬇ Download for 1.21.2–1.21.11 · Quilt
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Network-Protocol-Disconnect

Network Protocol Disconnect is a mod designed to enhance your multiplayer experience by preventing automatic disconnections caused by invalid server packets in Minecraft.

In Minecraft 1.20.5, Mojang introduced a change where any invalid data in packets sent from a server would result in an immediate client disconnect, disrupting gameplay and making it difficult to remain connected to servers with imperfect network handling.

With Network Protocol Disconnect, this issue is resolved by overriding the default behavior, allowing the game to continue running even when invalid packets are detected. Instead of disconnecting, the mod ensures no interruptions while still logging any issues for your review.

Network protocol errors aren’t all just caused by invalid packets sent from the server; they can also be triggered by other mods, conflicting configurations, or unexpected network conditions. Network Protocol Disconnect ensures that the network protocol error screen never appears, preventing forced disconnects regardless of the source. This means the mod can also stop other mods from triggering network protocol error disconnections, making it a vital tool for maintaining stable multiplayer sessions. Any issues that arise are still logged for debugging, but they will never interfere with your gameplay.

⚠️ Warning: By disabling the disconnect feature, you may remain connected to servers sending faulty or malicious packets. Use this mod at your own risk, especially when playing on untrusted or unknown servers. Always ensure you play on reputable servers to avoid potential security issues.

Ideal for players encountering frequent disconnects on modded or unstable servers!
