NoTimeOut

notimeout is a small server-side NeoForge mod for Minecraft 1.21.1.

It increases the server login, keep-alive, and network read timeout limits. This gives players more time to finish joining the server before Minecraft disconnects them for taking too long.

This can help players with weaker PCs, slow storage, heavy modpacks, or unstable connections, especially when joining a large modded server.

The timeout value can be changed in the generated common config file.
