How to Connect to the CardNexus VPN

The CardNexus VPN allows you to securely access internal services (databases, internal tools, etc.) from your computer. Follow the steps below to get connected.

Step 1: Download the AWS VPN Client

Download and install the AWS VPN Client desktop application for your operating system:

macOS (Apple Silicon): Download for macOS ARM64
macOS (Intel): Download for macOS x64
Windows (x64): Download for Windows
Windows (ARM64): Download for Windows ARM64
Linux (Ubuntu): Installation instructions

Step 2: Download the VPN Configuration File

Download the CardNexus VPN configuration file and save it somewhere you’ll remember (e.g. your Downloads folder).

Step 3: Import the Profile

Open the AWS VPN Client application.
Go to File > Manage Profiles.
Click Add Profile.
Give it a name (e.g. CardNexus VPN).
Select the .ovpn file you downloaded in Step 2.
Click Add Profile.

Step 4: Connect

Select the CardNexus VPN profile from the dropdown.
Click Connect.
A browser window will open — sign in with your CardNexus Google account.
Once authenticated, the client will show Connected.

You’re all set! You can now access internal CardNexus services.

Disconnecting

Click Disconnect in the AWS VPN Client when you no longer need access. The VPN uses split tunneling, so only traffic to internal services goes through the VPN — regular internet browsing is unaffected.

Troubleshooting

Issue	Solution
Browser doesn’t open on connect	Make sure your default browser is set and try again.
Authentication fails	Ensure you’re using your CardNexus Google account, not a personal one.
Connected but can’t reach services	Try disconnecting and reconnecting. If the issue persists, contact the infrastructure team.
Client shows “connection timed out”	Check your internet connection and retry. If on a restrictive network (hotel, airport), try a different network.
