        <h3>💡 温馨提示</h3>
        <p><strong>优选完成但测试"真连接延迟"为 -1？</strong>这很有可能是您的网络运营商对你的请求进行了阻断。</p>
        <p><strong>建议尝试以下解决方案：</strong></p>
        <ul>
            <li><strong>更换端口：</strong>尝试使用其他端口（如 2053、2083、2087、2096、8443）</li>
            <li><strong>更换IP库：</strong>切换到不同的IP来源（CM整理列表、AS13335、AS209242列表等，但如果你不明白AS24429和AS199524意味着什么，那就不要选。）</li>
            <li><strong>更换自定义域名：</strong>如果您使用的还是免费域名，那么您更应该尝试一下更换自定义域</li>
        </ul>
        <p>💡 <strong>小贴士：</strong>不同地区和网络环境对各端口的支持情况可能不同，多尝试几个端口组合通常能找到适合的IP。</p>
