How to Fix “Connection to the Game Server Lost” in ARC Raiders?

You’re playing ARC Raiders, everything feels smooth, and then suddenly you get the message: “Connection to the game server lost.” The match stops. You’re kicked out. It’s frustrating. Don’t worry. This guide explains what this error means, why it happens, and 7 practical fixes to restore your connection.

What Does “Connection to the Game Server Lost” Mean in ARC Raiders?

When ARC Raiders shows this message, it means your game client lost communication with the official multiplayer servers managed by Embark Studios and published under Nexon. The game constantly exchanges data with matchmaking servers and authentication servers to keep your session active. If that data flow breaks even for a few seconds, the server ends the session and disconnects you.

This usually relates to unstable internet, packet loss, firewall blocking, strict NAT type, or temporary backend maintenance. The error does not automatically mean your account is banned. It simply indicates that the server could not maintain a stable connection with your system.

You may see this message during a live match, while loading into a session, or even at the login screen. It can appear on PC through Steam or on consoles using PlayStation Network or Xbox Live.

Common Causes of ARC Raiders Server Disconnection

Server disconnections can happen because of both local network problems and server-side issues. Sometimes the ARC Raiders servers experience overload or maintenance. Other times, your router, ISP, or DNS settings interrupt communication. Multiplayer games rely on stable, low-latency connections. If packet loss increases or your NAT type restricts traffic, the server may terminate your session.

Below are the most common reasons players see this error.

Each of these affects how your system talks to the game server.

How to Fix “Connection to the Game Server Lost” in ARC Raiders?

Connection errors often relate to network stability or configuration settings. However, sometimes the problem comes from server downtime. Test each solution step by step. After trying one fix, reopen ARC Raiders and check if the issue is resolved.

Fix #1: Check ARC Raiders Server Status

Before adjusting your network, confirm that the servers are online. If Embark Studios is performing maintenance, no local change will help.

Follow these steps to check server status:

  1. Visit ARC Raiders official social media pages.
  2. Check Steam community announcements.
  3. Look for maintenance or outage reports.
  4. Confirm if other players report the same issue.
  5. Wait until servers are stable.

If servers are down, waiting is the only solution.

Fix #2: Restart Your Router and Modem

Network congestion or temporary IP conflicts can disrupt server communication. Restarting your router refreshes your connection with your ISP.

Here are the following steps which help you restart your network:

  1. Turn off your PC or console.
  2. Unplug your router and modem.
  3. Wait at least 60 seconds.
  4. Plug the router back in.
  5. Wait for full internet connection.
  6. Restart your device and launch the game.

This reset clears minor routing issues.

Fix #3: Switch to Ethernet Instead of Wi-Fi

Wi-Fi connections can drop packets or experience signal interference. Multiplayer games like ARC Raiders need consistent latency. A wired Ethernet connection provides a more stable data path between your device and the server. If possible, connect your PC or console directly to the router using an Ethernet cable. Then restart the game and test your connection again.

Fix #4: Change Your DNS Server

DNS servers translate domain names into IP addresses. If your ISP DNS misroutes requests, server communication may fail.

Follow the steps below to change DNS settings:

  1. Open Network Settings on Windows.
  2. Click Change adapter options.
  3. Right-click your active connection.
  4. Select Internet Protocol Version 4.
  5. Enter 8.8.8.8 and 8.8.4.4 as DNS addresses.
  6. Save settings and restart your PC.

This switches to Google Public DNS, which often improves routing reliability.

Fix #5: Allow ARC Raiders Through Firewall

Windows Defender Firewall may block outgoing multiplayer traffic. When this happens, authentication servers cannot verify your session.

Perform the following steps carefully:

  1. Open Control Panel.
  2. Click Windows Defender Firewall.
  3. Select Allow an app or feature.
  4. Find ARC Raiders in the list.
  5. Enable both Private and Public networks.
  6. Save changes and restart the game.

This ensures proper communication with the game server.

Fix #6: Disable VPN or Proxy

A VPN changes your public IP address and routes traffic through different regions. Sometimes game servers reject or delay these connections. If you are using a VPN service or proxy server, disable it temporarily. Restart your system, then relaunch ARC Raiders. If the error disappears, the VPN was interfering with routing.

Fix #7: Reset Network Settings

If nothing works, your network stack may be misconfigured. Resetting network settings restores default TCP/IP configuration and clears DNS cache conflicts. Open Windows Settings, go to Network and Internet, then choose Network Reset. Confirm and restart your PC. After rebooting, reconnect to Wi-Fi or Ethernet and test the game again.

Prevention Tips to Avoid Future Disconnections

Preventing disconnections keeps your multiplayer experience stable. Small maintenance steps reduce server communication problems.

Conclusion

In short, the “Connection to the game server lost” error in ARC Raiders means your client lost communication with the official multiplayer servers. The issue often relates to network instability, strict NAT type, firewall blocking, VPN routing, or server maintenance. Most players resolve it by checking server status, restarting their router, switching to Ethernet, or adjusting DNS settings.
