echo "1. Fix SilverPAY server (502 Bad Gateway):"
echo "   - SSH to Hostinger VPS: ssh -p 2255 sysadmin@31.97.57.205"
echo "   - Check Docker status: docker ps"
echo "   - Check logs: docker logs silverpay"
echo "   - Restart if needed: docker restart silverpay"
echo
echo "2. For Push Notifications (browser error):"
echo "   - The local endpoint works fine (/api/push/vapid-key)"
echo "   - The browser error is due to proxy/redirect to SilverPAY domain"
echo "   - Check if there's a proxy configuration redirecting API calls"
echo "   - Ensure the PWA is accessing the correct base URL"
echo
echo "3. Payment Provider Configuration:"
echo "   - Currently configured to use SilverPAY (UseSilverPay: true)"
echo "   - Will automatically fall back to BTCPay if SilverPAY fails"
echo "   - To force BTCPay: Set UseSilverPay: false in appsettings.json"

echo
echo "========================================================"
echo "6. TEST SUMMARY"
echo "========================================================"

echo -e "\n✅ Working:"
echo "   - Local application (port 8080)"
echo "   - Push notification endpoints (locally)"
echo "   - VAPID key generation"
echo "   - BTCPay fallback service"

echo -e "\n❌ Not Working:"
echo "   - SilverPAY server (502 Bad Gateway)"
echo "   - Browser push notifications (due to redirect to broken SilverPAY)"

echo -e "\n📝 Notes:"
echo "   - Application needs restart after adding new controllers"
echo "   - Port is 8080, not 5000 as originally expected"
echo "   - Payment system will use BTCPay until SilverPAY is fixed"
