🔎 What Is the “Server Login Failure” in Elden Ring: Nightreign?

The server login failure or server connection error in Elden Ring: Nightreign appears when the game can’t reach its matchmaking or authentication servers. This usually happens during patch rollouts, scheduled maintenance, or due to network configuration issues on the player’s side, like strict NAT types, blocked ports, or corrupted anti-cheat files. While it might look like a server-side bug, many cases are user-fixable with the right steps.

✅ Step-by-Step Fixes (From Easiest to Advanced)

---

1. Check If Servers Are Down First 🕒

Before tweaking your PC, verify if there’s scheduled maintenance:

• Check @ELDENRING on Twitter/X
• Visit Bandai Namco’s official status pages
• Look at gaming news outlets like PCGamesN or PCGamer
  

📌 Example: Servers went down June 6 and June 10, 2025 for updates and patch 1.01.2.

If servers are offline, wait until maintenance is over—no fix will work during downtime.

---

2. Restart Steam and the Game 🔄

This quick reset can trigger updates and refresh your client:

• Fully exit Steam
• Relaunch Steam and Elden Ring: Nightreign
• If prompted, install any pending updates

A Steam user reported that restarting Steam immediately triggered an update and fixed their connection error.

---

3. Verify Game Files 🧩

Corrupt or missing files can break server login:

1. Go to Steam Library
2. Right-click Elden Ring: Nightreign → Properties
3. Under Installed Files, click Verify integrity of game files

Let Steam fix or re-download anything missing. If the game still stutters or runs poorly even after verifying files, it might not be using your dedicated GPU properly. Check out this guide on what to do when Elden Ring isn’t using your GPU to ensure you’re getting peak performance.

4. Repair Easy Anti-Cheat (EAC) 🛠️

EAC issues often cause server login blocks:

• In Steam, right-click game → Browse Local Files
• Go to the EasyAntiCheat folder
• Run EasyAntiCheat_Setup.exe and select Repair for Elden Ring
  

Also:

• Locate EasyAntiCheat_EOS.exe (usually in C:\Program Files (x86)\EasyAntiCheat_EOS\)
• Right-click → Properties > Compatibility → Check Run as Administrator

Some users also run eldenring.exe and Steam.exe as admin for extra reliability. If you’re getting constant disconnects or can’t join sessions, it could be tied to a blocked anti-cheat service—here’s how to fix EAC error 20006 in Nightreign.

5. Disable VPNs and Proxies 🌍

Many server login failures happen because VPNs reroute traffic:

• Turn off any VPN, proxy, or internet “optimizer”
• Restart your PC and retry connecting

A VPN can introduce latency or IP mismatches that get flagged by anti-cheat or the login server.

---

6. Allow the Game Through Windows Firewall 🔐

To whitelist the game manually:

• Open Windows Defender Firewall
• Click “Allow an app or feature…”
• Ensure both eldenring.exe and the EasyAntiCheat EXE are allowed for Private and Public networks
• If not listed, click Add another app and browse manually

Repeat this step in any third-party antivirus software, too.

---

7. Reset Network Stack & DNS Cache 🌐

Run the following commands in Command Prompt as Administrator:

• netsh winsock reset
• ipconfig /flushdns

Then reboot your PC. These commands clear corrupt TCP/IP settings and refresh your DNS.

✅ Bonus Tip: Change your DNS servers to:

• Primary: 8.8.8.8
• Secondary: 1.1.1.1

Set them in your IPv4 adapter settings to avoid ISP-related DNS timeouts.

---

8. Check NAT Type & Router Config ⚙️

Nightreign uses peer-to-peer networking, so NAT restrictions block logins.

To check NAT:

1. Open Command Prompt
2. Run:
   • netsh interface Teredo show state

If you see NAT: Strict, do this:

• Enable UPnP in your router settings
• If unavailable, forward ports:
  • TCP/UDP: 27015–27050 (Steam)
  • Ensure EAC ports are also open

Or place your PC into DMZ mode temporarily for full access (refer to your router manual).

---

9. Reboot Router or Switch Networks 🔁

Simple network glitches also cause server failures:

• Power off your modem/router for 30 seconds, then restart
• Try switching from Wi‑Fi to Ethernet or vice versa
• Some players reported bizarre fixes just by toggling Wi‑Fi

---

10. Tweak In-Game Matchmaking Settings 🎮

Go to Settings > Network:

• Toggle “Cross-Region Play” off (or on)
• Toggle “Cross-Country Matchmaking” as needed

🧪 Experiment: Some users fixed login errors by changing only these settings, then restarting the game.

This trick will can also work when you’re dealing with multiplayer connection issues or Elden Ring crashing on PC.

11. Expedition Search Won’t Match? ❌

If you’re stuck at the Expedition matchmaking screen:

• Cancel the expedition
• Quit to Main Menu
• Re-launch matchmaking after a fresh reboot

---

12. Still Not Working? Try These Final Tips 🧠

• Play during off-peak hours — Nightreign servers can get overloaded
• Check Downdetector for player reports of outages
• Contact Bandai Namco Support if all else fails (attach logs)
