Nuclear Option

Nuclear Option server not showing up or unable to connect

Use Nuclear Option’s multiplayer browser or the assigned connection address. Check Modded Server when comparing browser filters and client content; a modded session may be excluded by the player’s filters.

If joining fails

The installed template uses DedicatedServerConfig.json and a separate query allocation. If the listing is visible but a mission fails to load, inspect the selected mission content rather than the browser port.

  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.
