Hello there, Thank you for reaching out. NIGHTINGALE means the game client can’t download required config files from Bungie’s servers, usually due to DNS/firewall/network issues rather than your install itself. Since you’re on PC/Steam and already did the basics, try these in order: Fully power-cycle network + PC Shut down PC. Unplug router/modem for 60 seconds, plug back in, wait until fully online. Boot PC and try Destiny 2 again. Change DNS to Google DNS (very often fixes NIGHTINGALE) Open Control Panel → Network and Sharing Center → Change adapter settings. Right-click your active connection → Properties. Select Internet Protocol Version 4 (TCP/IPv4) → Properties. Choose Use the following DNS server addresses and set: Preferred: 8.8.8.8 Alternate: 8.8.4.4 Click OK on all dialogs, then restart your PC and launch Destiny 2. Clear Steam download cache In Steam: Steam → Settings → Downloads → Clear Download Cache. Steam will restart; log back in and try Destiny 2. Test a different network path Temporarily connect via phone hotspot or a different network to see if you can get past the error. If it works there, your home network/router is blocking or timing out the config download. Check firewall / security software Temporarily disable third-party antivirus/firewall or add exceptions for: destiny2.exe Steam Ensure your router isn’t using aggressive filtering, parental controls, or a VPN/proxy that could block Bungie traffic. Last-resort reinstall If all of the above fail, fully uninstall Destiny 2 and reinstall. After reinstall, try with Google DNS still set. If you run through all of this and NIGHTINGALE still appears on multiple networks, that strongly suggests either: an ISP-side routing/DNS problem, or a local hardware issue (SSD, NIC, or router).
