- A minecraft server is running on the local network, but the Minecraft client can't find server on the local LAN.
- on MacOS, Java uses IPv6 by default for service discovery, but the server is only announced over IPv4.
- Force Java on the client to prefer IPv4.
- Steps to fix
- Quit Minecraft and open the Minecraft Launcher
- Select the Minecraft "Installations" tab.
- Edit the installation that you are normally playing
- Select "More options"
- At the "JVM arguments" append the text ` -Djava.net.preferIPv4Stack=true`. In my case, the whole line now reads `-Xmx4G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn256M -Djava.net.preferIPv4Stack=true`
- Save and start Minecraft.
The pages list specific bug reports. I try to keep this category empty by reporting bugs directly to the developers database.
