About this Mod

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!

Frequently Asked Questions

Does Network Protocol Disconnect need to be installed on the Minecraft server?

No. Modrinth marks Network Protocol Disconnect as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Network Protocol Disconnect require?

Use a file for fabric, neoforge, quilt and your exact Minecraft version. Supported versions include 26.2, 26.1.2, 26.1.1. Files for different loaders are not interchangeable.

Network Protocol Disconnect is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
