echo "8. Troubleshooting:"
echo "   If uploads still show 'endless encryption':"
echo "   → Check if upload is actually starting (monitor nginx logs)"
echo "   → Verify ejabberd is sending correct HMAC signatures"
echo "   → Test with smaller file first to isolate the issue"

# Test suggestions
echo "9. Next Steps:"
echo "   1. Try uploading a small test file first"
echo "   2. Monitor logs during upload: sudo tail -f /var/log/nginx/share_access.log"
echo "   3. Check HMAC signature validation in server logs"
echo "   4. Verify ejabberd cluster is generating valid upload URLs"

echo "=== Verification Complete ==="
echo "All optimizations are in place. The 1GB deduplication limit should"
echo "eliminate the 'endless encryption' delay for your large video files."
