Fixing OpenVPN Connection Issues in Ubuntu 24.04

If you've recently upgraded to Ubuntu 24.04 and found your OpenVPN connections failing silently, you're not alone. Here's a quick fix that resolved this common issue.

The Problem:

  • Silent VPN connection failures after importing .ovpn configuration files
  • No error messages to indicate the cause
  • Affects users who upgraded to Ubuntu 24.04

The Solution:

The fix involves updating a single line in your .ovpn configuration file. You'll need to replace the older cipher directive with a newer data-ciphers-fallback directive.

1. Edit the .ovpn Configuration File:

The key to resolving the issue lies in replacing the cipher directive with the data-ciphers-fallback directive. This change ensures that OpenVPN falls back to the specified cipher if the client and server cannot agree on a shared cipher.

before:

cipher AES-256-CBC
Enter fullscreen mode Exit fullscreen mode

After

data-ciphers-fallback AES-256-CBC
Enter fullscreen mode Exit fullscreen mode
