How to troubleshoot connection issues on NordVPN
Quick Answer
NordVPN connection issues can usually be resolved by checking your internet connection, switching servers, or adjusting protocol settings. Most problems are fixed by restarting the app, clearing cache, or changing connection protocols from OpenVPN to NordLynx.
Prerequisites
- Active NordVPN subscription
- NordVPN app installed on your device
- Basic knowledge of network settings
- Administrator access to your device
1
Check Your Basic Internet Connection
Before troubleshooting NordVPN specifically, verify your internet works without the VPN. Disconnect from NordVPN by clicking Disconnect in the app, then test browsing to
google.com or run ping 8.8.8.8 in Command Prompt/Terminal. If there's no internet, contact your ISP first.Tip
Run a speed test without VPN to establish baseline connection quality.
2
Restart NordVPN Application
Close NordVPN completely and restart it. On Windows, right-click the system tray icon and select Quit NordVPN. On Mac, press Cmd+Q while the app is active. On mobile, force-close the app from recent apps. Wait 10 seconds, then relaunch NordVPN and try connecting again.
Tip
This clears temporary connection states that may be causing issues.
3
Switch to Different Server Locations
In the NordVPN app, click Country List or the map view. Try connecting to a different server in the same country first, then try servers in different countries. Click on a country, then select Quick Connect or choose a specific server from the list. Test 3-4 different servers to isolate server-specific issues.
Tip
Servers closer to your physical location typically provide better speeds and stability.
4
Change VPN Protocol Settings
Open NordVPN settings by clicking the gear icon or Settings. Navigate to Auto-connect or Protocol section. If using NordLynx, switch to OpenVPN (UDP). If using OpenVPN, try OpenVPN (TCP) or switch to NordLynx. Save settings and attempt reconnection.
Tip
TCP protocol is more stable but slower, while UDP is faster but less reliable on unstable connections.
5
Disable Conflicting Software
Temporarily disable antivirus software, firewall, or other VPN applications that might conflict. In Windows Defender, go to Virus & threat protection > Manage settings and disable Real-time protection. Check if other VPN clients like ExpressVPN or Surfshark are running and close them completely.
Tip
Remember to re-enable your antivirus after testing.
6
Clear NordVPN Cache and Reset Settings
In NordVPN app settings, look for Advanced or General section and click Reset app settings or Clear cache. On Windows, you can also delete temporary files by pressing Win+R, typing
%temp%, and deleting NordVPN-related folders. Restart the app after clearing cache.7
Update NordVPN and Network Drivers
Check for app updates in Settings > General > App updates or download the latest version from nordvpn.com. Update your network adapter drivers through Device Manager on Windows or Software Update on Mac. Restart your device after updates complete.
Tip
Enable automatic updates in NordVPN settings to prevent future compatibility issues.
Troubleshooting
Connection keeps dropping every few minutes
Switch to OpenVPN TCP protocol and enable Kill Switch in settings. Also check if your router has VPN blocking enabled.
Can't connect to any servers
Flush DNS cache by running
ipconfig /flushdns on Windows or sudo dscacheutil -flushcache on Mac. Try connecting through mobile hotspot to test ISP blocking.Very slow speeds when connected
Try NordLynx protocol, connect to less crowded servers, and disable unnecessary features like Obfuscated servers unless needed.
