ConnectivityFixes "lost connection: timed out" disconnects on big packs

Version: 5.5 · MC 1.21.1 · NeoForge 21.1.234 · Java 21

About

Patches the keep-alive timeout that vanilla applies during initial login. On heavy modpacks like ATM10, login can take 30-60 s while client and server sync chunks/data; vanilla times out at 30 s and kicks you. Connectivity bumps the limit and improves timing.

Getting started

Auto-loads with the pack. Open JEI/EMI and search for the mod name to see all the items and recipes it adds.
