A comprehensive guide to solving OpenVPN Connect 3.4+ compatibility issues with older VPN profiles. Learn three proven methods to fix the "unknown/unsupported option" error and restore your VPN connectivity.

Introduction

Since the release of OpenVPN Connect version 3.4 in July 2023, many users have encountered unexpected connectivity issues with their previously working VPN profiles. If you're seeing error messages like "unknown option" or "unsupported option" when trying to connect, you're not alone.

This comprehensive guide explains why this problem occurs and provides three effective solutions to get your VPN connections working again. Whether you're a networking professional or an everyday VPN user, you'll find straightforward, actionable fixes here.

Applies to: OpenVPN Connect version 3.4 and later on Windows, macOS, Linux, iOS, and Android.

Understanding the Issue

The root cause of this problem is a significant change in how OpenVPN Connect handles configuration options. Starting with version 3.4, the client no longer supports several configuration directives that were common in older profiles.

When you attempt to connect using an older profile that contains these now-unsupported options, OpenVPN Connect fails with errors like:

Error: unknown option or missing parameter(s) in [CONFIG-FILE]:XX: route-delay (2.6.8)

Error: unknown option or missing parameter(s) in [CONFIG-FILE]:XX: pull (2.6.8)

The two most common problematic directives are route-delay and pull, though you might encounter issues with other options as well.

The good news is that these directives are often not critical to establishing a secure connection, which means we can address the issue with some straightforward modifications.

Solution 1: Edit OpenVPN Profile

The most direct solution is to edit your OpenVPN profile (.ovpn file) to remove the unsupported directives. This approach requires no additional software and works with your existing OpenVPN Connect installation.

Step-by-Step Instructions:

  1. Locate your .ovpn profile file

    If the file is already on your device, find it in your file manager. If it's in the OpenVPN Connect app, you'll need to export it first.

  2. Open the file in a text editor

    Use any plain text editor like Notepad (Windows), TextEdit (Mac), or any code editor. Right-click the .ovpn file and select "Open with" to choose your text editor.

  3. Remove problematic lines

    Look for and delete any lines containing:

    • route-delay (may appear as route-delay 2 or similar)
    • pull (usually appears on its own line)

    - route-delay 2

    - pull

  4. Save the modified file

    Save the file with the same name or a new name if you want to keep the original as a backup.

  5. Import the modified profile into OpenVPN Connect

    In the OpenVPN Connect app, import the modified profile and attempt to connect again.

Pro Tip: Make a backup of your original .ovpn file before making any edits. This way, you can always revert to the original if needed.

This solution is ideal for users who need to continue using OpenVPN Connect 3.4+ and don't want to switch to alternative clients.

Solution 2: Use an Alternative OpenVPN Client

If you prefer not to modify your VPN profiles or if you're managing multiple profiles, switching to an alternative OpenVPN client might be more efficient. The OpenVPN Community client maintains better compatibility with older profile configurations.

OpenVPN Community Client

  • Full compatibility with older profiles
  • Advanced configuration options
  • Available for Windows, macOS, and Linux

Other Compatible Clients

  • Tunnelblick (macOS) -Download
  • Viscosity (Windows/macOS) -Download
  • NetworkManager with OpenVPN plugin (Linux) - Available in most Linux package managers

Installation Steps (OpenVPN Community Client):

  1. Download the appropriate installer for your operating system from the link above
  2. Run the installer and follow the on-screen instructions
  3. Import your existing .ovpn profile files without modifying them
  4. Connect using the new client with your original credentials

The OpenVPN Community client offers a more traditional interface with additional configuration options, which some advanced users might prefer over the simplified OpenVPN Connect application.

Solution 3: Downgrade OpenVPN Connect

If you specifically need to use OpenVPN Connect (rather than the Community client) and don't want to modify your profiles, downgrading to an earlier version of OpenVPN Connect (pre-3.4) is another viable option.

Security Note: Using older software versions may expose you to security vulnerabilities that have been patched in newer versions. Only use this approach if you understand and accept the potential risks.

Legacy versions of OpenVPN Connect can be found on various software archive sites, but we recommend obtaining them directly from OpenVPN's official archives when possible to avoid potential security risks from unofficial sources.

Downgrade Steps:

  1. Uninstall your current version of OpenVPN Connect
  2. Download a pre-3.4 version from a trusted source
  3. Install the older version
  4. If prompted to update, decline automatic updates
  5. Import your original .ovpn profile

This solution is best considered temporary while you either adapt your profiles for compatibility with newer versions or transition to the OpenVPN Community client.

Why These Solutions Work

To understand why these fixes are effective, it helps to know what the problematic directives actually do:

DirectiveFunctionWhy It Can Be Removed
route-delayDelays the addition of routes until after TUN/TAP device is openedOpenVPN Connect 3.4+ manages route timing automatically, making this directive unnecessary
pullAccepts options pushed by the serverThis behavior is now the default in OpenVPN Connect 3.4+, making the explicit directive redundant

In essence, OpenVPN Connect 3.4+ has integrated these functions into its core behavior, making the explicit directives unnecessary and, ironically, causing them to be flagged as errors when encountered in configuration files.

By removing these now-redundant directives, Solution 1 allows your profiles to work with the newer OpenVPN Connect versions without actually changing the functional behavior of your VPN connection.
