Just Cause 3 Multiplayer

Fix Just Cause 3 Multiplayer settings that revert at startup

The template writes server identity and network values to config.json and supplies additional limits on the command line. Use the matching Startup fields for managed values instead of editing only the JSON.

File locations used below — relative to the server root
config.json

Make the change

  1. Stop the server and download a copy of config.json plus your resource configuration.
  2. Change Server Name, Server Description or Server Password through Startup where exposed.
  3. For other JSON settings, preserve the existing structure, quotes and commas.
  4. Keep allocated ports unchanged while testing an unrelated name or description edit.
  5. Start and check both the server listing and a client connection after resource loading completes.

Server NameThe name players see when looking for the session. Use a distinctive name so it is easy to distinguish from other servers.

Check the result

If JSON parsing fails, restore the copied config and repeat one edit. If resources fail after the connection, investigate their own configuration rather than repeatedly changing the server name.
