Copy buttons also appear in the sidebar. Bookmark this page so friends always get the current IP if the hostname ever changes.

Last ping reported software/version string: §4Deleted. A version mismatch is one of the most common reasons a correct IP still fails to connect.

Yes — combat is part of how Unstable Core is categorized (Survival), with related tags like semi-vanilla, anarchy.

That usually means PvP exists somewhere on the network (war zones, arenas, or open world). Always read spawn/safe-zone rules on this page or in Discord before fighting — many servers punish combat logging or spawn camping.

Our last successful ping for Unstable Core reported version §4Deleted. That string comes from the live server, so it is the most reliable clue when Multiplayer says “outdated client” or “outdated server”.

If join fails with a version error, update or downgrade Minecraft to match the ping string above, then retry the same IP.
