Problem
Your internet is slow when connected to a VPN server on NordVPN’s Linux app.
Common symptoms
- Your download and upload speed test results are lower than usual.
- Websites and streaming videos take longer than usual to load.
Troubleshooting steps
NOTE: Check your connection speed on speedtest.net after each step.
NOTE: It is possible to experience an increase in ping when connecting to a country far away from your physical location.
- If you used the “Secure my connection” button to connect to the VPN, try manually selecting and connecting to countries closest to your physical location instead.
- Change the VPN protocol:
- Open the NordVPN app.
- Click “Settings” on the left side of the app.
- Click “VPN connection.”
- Try connecting with all available protocols.
- Connect to an obfuscated server:
NOTE: Obfuscation is only available with the OpenVPN protocol.
- Open the NordVPN app.
- Click “Settings” in the left-side column.
- Click “Security and privacy.”
- Enable “Obfuscation.”
- Click the “VPN” tab in the upper-right corner.
- Click “Specialty servers.”
- Connect to an obfuscated server.
-
Clean all firewall rules from your device by entering these commands into the terminal one by one:
NOTE: Resetting the rules may affect DNS traffic.
sudo iptables -F INPUT
sudo iptables -F OUTPUT
sudo iptables -P INPUT ACCEPT
sudo iptables -P OUTPUT ACCEPT
sudo iptables -F -t mangle
sudo systemctl restart NetworkManager
Additional tips
- If the issue appeared after you tried to connect to the same VPN server multiple times, wait a few minutes before attempting to connect again.
- Check if the issue occurs on other devices connected to the same network. If it does, try switching to a different network.
- Check your internet connection without connecting to the VPN.
