Connectivity

Connectivity is a lightweight Minecraft mod that addresses login timeouts, DecoderException errors, packet size limits, and ghost blocks. Network statistics and detailed error logging help trace connection problems. Available for Forge, NeoForge, and Fabric on Minecraft 1.18.2–26.3, newer releases require the Cupboard dependency.

Rent your own Minecraft server and install Connectivity with one click from the panel to investigate network traffic and tackle connection errors.
