How to fix DNF error 'You have been disconnected. Please check your network connection.'

If you get a DNF "disconnected" error, try these steps: 1. Restart your network adapter. 2. Flush DNS and reset TCP/IP. 3. Allow DNF through firewall/antivirus. 4. Use Ethernet instead of Wi-Fi. 5. Block problematic domains via the hosts file.

If you're encountering a DNF error stating "You have been disconnected. Please check your network connection," it may not always be a network issue. Here are effective ways to resolve it.

The operating environment of this tutorial: Dell XPS 13, Windows 11

1. Restart Your Network Adapter

Resetting your network adapter can clear temporary glitches that disrupt DNF's connection to the server. This action refreshes the network stack and re-establishes a clean connection.

• Press Windows X and select "Network Connections."
• Click "Change adapter options."
• Right-click your active network connection and choose "Disable."
• Wait 10 seconds, then right-click and select "Enable."

2. Flush DNS and Reset TCP/IP

Corrupted DNS cache or misconfigured TCP/IP settings can interfere with DNF's ability to maintain a stable connection. Clearing these settings forces your system to rebuild them correctly.

• Open Command Prompt as Administrator.
• Type ipconfig /flushdns and press Enter.
• Then type netsh int ip reset and press Enter.
• Follow with netsh winsock reset and restart your computer.

3. Add DNF to Firewall and Antivirus Exceptions

Overprotective security software might block DNF’s network access, triggering disconnection messages. Granting explicit permission ensures uninterrupted communication.

• Open your firewall or antivirus settings.
• Navigate to application or program control.
• Locate DNF in the list or manually add its executable file.
• Set both inbound and outbound access to "Allow."

4. Use a Wired Connection Instead of Wi-Fi

Wireless networks are more prone to interference and latency spikes. Switching to an Ethernet connection improves stability and reduces packet loss during gameplay.

• Connect your device to the router using an Ethernet cable.
• Disable Wi-Fi to ensure traffic routes through the wired interface.
• Launch DNF and check if the disconnection persists.

5. Modify Hosts File to Block Problematic Domains

Some external domains may interfere with DNF’s authentication process. Blocking them via the hosts file can prevent unwanted redirects or timeouts.

• Navigate to C:\Windows\System32\drivers\etc\hosts.
• Open the hosts file with Notepad as Administrator.
• Add the following line at the end: 0.0.0.0 pallas.dnf.gamedn.com.
• Save the file and restart the game.
