Verify a successful ProtonVPN connection

Visit ProtonVPN’s IP Check from a private/incognito browsing window to verify your new IP address and virtual location.

In some cases you may notice that the location is not showing the same location as the server you have input in your router settings; this is because geo tracking tools are often tricked by VPN connections. As long as you see an IP address that is not the same as your normal Internet IP address then you are indeed connected to ProtonVPN.

How to change the ProtonVPN server

  1. Follow the steps at the top of the page to obtain a new .conf file.
  2. Then proceed with the settings same as initial setup.

Surfshark Setup for Privacy Hero

· ·

Privacy Hero supports Surfshark through WireGuard and OpenVPN using the Custom VPN provider option.

WireGuard is recommended for most users. It requires a Surfshark WireGuard key pair and a downloaded server configuration file. OpenVPN uses a downloaded .ovpn file and Surfshark’s separate Manual Setup credentials, not your usual Surfshark login email and password.

Privacy Hero is cloud-managed. You can change these settings from any computer, smartphone, or tablet with an internet connection; you do not need to be on the Privacy Hero WiFi to configure the VPN.

Surfshark WireGuard Setup (Recommended)

WireGuard uses a key pair for authentication. A separate Surfshark username and password is not needed for the WireGuard configuration.

Create or Select Your Surfshark WireGuard Key Pair

  1. Sign in to your Surfshark account.
  2. Open VPN → Manual Setup, choose the Router setup option, and select WireGuard.
  3. If you already registered a key pair with Surfshark, select I have a key pair and follow the prompts to register your public key. Otherwise, select I don’t have a key pair.
  4. If generating a new key pair, enter a name and choose Generate a new key pair. Save the generated keys securely when prompted.

Important: Your WireGuard private key is sensitive. Do not publish or send it in a support ticket. Surfshark notes that you may not be able to view the generated keys again after leaving that screen.

Download a Surfshark WireGuard Server File

  1. After setting up the key pair, select Choose a location or open the Locations section.
  2. Choose an available Surfshark server and download its WireGuard configuration file to your device.

Do not download the WireGuard configuration before setting up the key pair. Surfshark warns that a file downloaded too early can be missing the required key information. For more detail, see Surfshark’s manual WireGuard router instructions.

Upload WireGuard to Privacy Hero

  1. Open app.privacyhero.com and log in to your Privacy Hero account.
  2. Open the VPN section, click Change, and choose Custom as the VPN provider.
  3. Select WireGuard and upload the Surfshark WireGuard configuration file you downloaded.
  4. Click Save and allow Privacy Hero to establish the connection. Confirm the VPN status shows Connected.
Privacy Hero Custom WireGuard configuration and file upload panel

Surfshark OpenVPN Setup

OpenVPN is an alternative to WireGuard. It requires a Surfshark Manual Setup username and password and a downloaded OpenVPN configuration (.ovpn) file.

Get Your Surfshark OpenVPN Credentials

  1. Sign in to your Surfshark account.
  2. Open VPN → Manual Setup, choose Router, and select OpenVPN.
  3. Open the Credentials tab. If credentials are not yet available, select Generate credentials.
  4. Copy the Manual Setup username and password, or keep the tab open to enter them into Privacy Hero later.

Important: These are not your regular Surfshark website email and password. Keep the service credentials private.

Download a Surfshark OpenVPN Server File

  1. In Surfshark’s OpenVPN Manual Setup area, open the Locations tab.
  2. Select a country or server and download its UDP .ovpn configuration file. UDP is the recommended starting option; a TCP configuration may be worth trying later if needed.

Download a new .ovpn file whenever you want to switch to a different Surfshark server location. See Surfshark’s manual server selection instructions.

Upload OpenVPN to Privacy Hero

  1. Open app.privacyhero.com, sign in, and select the VPN section.
  2. Click Change, select Custom, and choose OpenVPN.
  3. Upload the Surfshark UDP .ovpn file you downloaded.
  4. Enter the Surfshark Manual Setup username and password into the Custom OpenVPN fields.
  5. Click Save, then confirm the VPN status shows Connected.

Verify Your Surfshark Connection

Privacy Hero showing Connected confirms the router connection status. Test a device on the Privacy Hero network to confirm it is using Surfshark.

  1. Connect your device to the Privacy Hero WiFi or LAN.
  2. Disconnect the Surfshark app or any other VPN app running directly on the testing device.
  3. Open a fresh private/incognito browser window.
  4. Visit Surfshark’s IP address checker.
  5. Confirm the displayed public IP and approximate location correspond to your selected Surfshark server.

You can change Privacy Hero settings while using another WiFi network or cellular data, but the device performing this VPN IP test must be connected to Privacy Hero. Avoid running a separate VPN app on the same testing device, as that creates a double-VPN connection.

Streaming Relocation and Your VPN Location

When Streaming Relocation is enabled for a supported streaming service, that service may use its Streaming Relocation region instead of the Surfshark VPN server region. See Privacy Hero Streaming Relocation.

Surfshark Not Connecting?

If Privacy Hero displays Failed, remains on Connecting, or reports a timeout, try these steps:

  1. Confirm your Surfshark subscription is active and that Custom is selected as the VPN provider in Privacy Hero.
  2. If using WireGuard, confirm that the key pair was created or registered before downloading the server file. If necessary, generate a new key pair, download a fresh configuration, and upload it again.
  3. If using OpenVPN, double-check your separate Surfshark Manual Setup username and password, not your regular website login.
  4. Download a fresh server configuration for another available Surfshark location and try again.
  5. If OpenVPN UDP continues to fail, try a Surfshark TCP .ovpn configuration file to check for a protocol-specific issue.
  6. Temporarily disable the VPN Kill Switch while checking whether internet access works without the VPN, then restore your preferred Kill Switch setting.

No Internet After Surfshark Disconnects?

The VPN Kill Switch may intentionally block normal internet traffic when the VPN connection is unavailable. See Privacy Hero VPN Kill Switch: No Internet or WiFi Troubleshooting.

VPN Connected but One Device Shows the Wrong IP?

If other Privacy Hero devices display the expected Surfshark VPN IP, review the affected device for VPN apps, iCloud Private Relay, Private DNS, proxy settings, antivirus filtering, or other security software. See Device Settings That Can Interfere With Your Router VPN.
