# Troubleshooting

> Solutions for common Maximum VPN issues

Here are solutions for the most common issues when using Maximum VPN. If none of the solutions help — contact [support](/en/help/support).

<AccordionGroup>
  <Accordion title="VPN does not connect">
    **Possible causes and solutions:**

    1. **No internet connection.** Make sure your device is connected to Wi-Fi or mobile data without VPN.

    2. **Server temporarily unavailable.** Try switching to a different server in the Happ app. We recommend servers in the Netherlands — the largest cluster with high availability.

    3. **Outdated configuration.** Remove the current configuration from Happ and re-import the subscription link from the [dashboard](https://app.maximum-vpn.com).

    4. **Outdated Happ version.** Update the app to the latest version via the App Store, Google Play, or the official website.

    5. **Network-level blocking.** If you are on a corporate or restricted network, try connecting via mobile data.
  </Accordion>

  <Accordion title="Slow connection speed">
    **What to try:**

    1. **Switch servers.** Choose the geographically closest server. For users in Russia and CIS countries, we recommend Finland, Latvia, or Lithuania.

    2. **Check your base speed.** Disconnect the VPN and check your internet speed. If it is low — the problem is on your ISP's side.

    3. **Restart the connection.** Disconnect the VPN, wait a few seconds, and reconnect.

    4. **Avoid busy servers.** If one server is slow, try another in the same country.

  <Accordion title="Happ app won't launch">
    **Solutions by platform:**

    * **iOS:** Make sure you have iOS 15.0 or later. Try deleting and reinstalling the app.
    * **Android:** Clear the app cache (Settings -> Apps -> Happ -> Clear cache). Reinstall if needed.
    * **Windows:** Make sure you have Windows 10 or later. Run the installer as administrator. Check if your antivirus is blocking the app.
    * **macOS:** Make sure the app is in the Applications folder. If blocked by the system, go to Settings -> Privacy & Security -> allow the launch.

    3. Request a resend of the email on the login page.
