Common Issues on Linux

DNS, cipher and Network Manager troubleshooting for Ubuntu and Mint.

Step-by-step

3 steps
1

DNS not routing through the tunnel

Install the update-resolv-conf helper and add “up/down” lines to your .ovpn so DNS follows the VPN. Alternatively set a public resolver on your connection.

2

Cipher negotiation failed

On newer releases add tls-cipher=DEFAULT:@SECLEVEL=0 to the connection (see the 22.04 fix guide).

3

VPN option missing

If OpenVPN never appears in Network Manager, install network-manager-openvpn-gnome and restart NetworkManager: sudo systemctl restart NetworkManager
