- Pick another server from the list in Happ — the current one may have become unavailable.
- Check ping: tap the speedometer icon in the subscription header — the delay appears next to each server; pick one without "Timeout".
- Refresh the subscription in Happ — the ⟳ icon in the header (servers may have changed).
- Make sure the subscription is active — the status on the subscription card on the Home tab of lk.surfingvpn.com.
- If nothing helped — re-issue the subscription (Home → subscription card → "Manage" → "Re-issue subscription") and add it to Happ again.
