Packet Fixer increases packet size limits to prevent errors involving oversized NBT data, chunk packets and payloads. It can help modpacks accommodate more mods and must be installed on both the client and server.
Available for Fabric, Quilt, NeoForge and Forge, it supports Minecraft 1.12.2–26.3.
Give your rented Minecraft server more room for modded packet data by installing Packet Fixer with one click from the server panel.
