Mod Packet Fixer

Packet Fixer, a mod for smoother modded servers

Packet Fixer is a technical Minecraft mod designed to solve communication problems between the game client and server. It raises packet size limits and helps prevent errors linked to oversized NBT data, compressed packets, large payloads, VarInt values, and chunks that require excessive memory.

Compatible with Fabric, Forge, NeoForge, and Quilt, the mod supports both client and server environments. It is especially useful for large modpacks, complex machines, detailed entities, and heavily developed worlds where strict network limits can cause disconnects, crashes, or connection timeouts. At BoxToPlay, we recommend it for a more reliable Minecraft server experience.
