Here are solutions for the most common issues when using Maximum VPN. If none of the solutions help — contact support.
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 Outdated configuration.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.
  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 Outdated Happ version.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.
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.
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.
If the VPN is connected but the internet isn’t working:
  1. Try switching to a different server in the Happ app.
  2. Disconnect and reconnect the VPN.
  3. Check that the internet works without VPN.
  4. Refresh the configuration — re-import the subscription link from the dashboard.
  1. Check your Spam / Junk folder.
  2. If you are using mail.ru, bk.ru, list.ru, or inbox.ru — emails may be delayed or end up in spam.
  3. Request a resend of the email on the login page.
  4. If the email doesn’t arrive — try registering via Google or Telegram.
After updating Happ, you may need to refresh the configuration:
  1. Open Happ.
  2. Remove the current configuration (subscription link).
  3. Re-import the subscription link from the dashboard.
  4. Connect to a server.
