Stationeers Connection Timeout Fix: GamePort, UpdatePort & Firewall

Stationeers Guide • Updated Aug 22, 2026

Stationeers Connection Timeout Fix

Stationeers has two network values that are easy to swap: GamePort carries game traffic and UpdatePort is used by the Steam update/query path. Open both values that the server actually uses.

Connection path checklist

  1. Confirm the process is running and the station has loaded.
  2. Check GamePort and UpdatePort in the active launch configuration.
  3. Allow both UDP ports through the host firewall and router.
  4. Use the public address, not a private LAN address, from outside the network.
  5. Compare client and server branches before changing world files.

Do not use a TCP-only port checker to validate Stationeers’ UDP game path. Use a real client and the assigned values.
