How to Fix Nightingale Connection Error

Here are the best solutions to fix the Nightingale connection error.

1. Do the basic troubleshooting. Try these quick checks to resolve the connection error.

  • Restart the game and PC or Console.
  • Check whether the game servers are down. You can check the Nightingale official Twitter page for updates regarding the status.
  • Ensure your internet connection is stable.

2. Verify the integrity of game files. If your game files are corrupted or missing, use the game launcher to verify and repair them. Here’s how:

  • Open Steam and go to your Library.
  • Right-click on Nightingale.
  • Select Properties, then navigate to Local Files.
  • Click on Verify Integrity of Game Files.
  • Wait for the process to finish.
  • Restart your computer when it’s done.

3. Add Nightingale as an exception in Windows Firewall. You can whitelist the Nightingale application in Windows Firewall to prevent server connectivity or game startup problems in most cases.

  • Open the Start menu and search for Control Panel.
  • In the Control Panel, go to Systems and Security, then open Windows Firewall.
  • Select Allow an app or feature through Windows Firewall.
  • Click on Change settings and then choose Allow another app.
  • Browse and select Nightingale.
  • Click Add and remember to save your changes.

4. Temporarily disable antivirus protection. Temporarily disable Windows Security to prevent multiplayer connectivity issues in Nightingale. Aggressive antivirus blocking can interfere with the game. Follow these steps to disable antivirus protection.

  • To access Windows Settings, press the Win+I keys.
  • Navigate to Update & Security > Windows Security.
  • Click on Open Windows Security.
  • Proceed to Virus & Threat Protection > Manage settings.
  • Turn off the Real-time protection toggle.
  • If prompted, click Yes.

Note: For third-party antivirus software, manually disable real-time protection to resolve program-blocking issues.

5. Run the game as an administrator. If you don’t run the game with administrator privileges, it can lead to launching issues, startup crashes, or even failure to load. To resolve this, run the game’s .exe file as an administrator on your Windows PC. Here’s how:

  • Right-click on the Nightingale exe shortcut file.
  • Select Properties > Compatibility tab.
  • Check Run this program as an administrator.
  • Click Apply and then OK to save changes.
