Core Keeper

Core Keeper server not showing up or unable to connect

Core Keeper players normally join with the Game ID. Read the current ID after the server finishes starting. The template removes and regenerates GameID.txt on startup, and an empty or invalid Game ID field can result in a different ID.

If joining fails

An old shared Game ID can fail even when the server is online. Check the current value first, then compare client versions. Changing World Index to solve a connection issue can load a different save.

  1. Open Console and wait for the game or world to finish loading. Save the first error if startup stops.
  2. Use the joining method above with one client on the matching game version and required content.
  3. If entry is rejected, compare the exact error with the password, edition, map or authentication checks above. Keep the working save while testing.
Open Startup → Variables for the controls exposed by this server. This demonstration hides private values; file edits are made through Files.
