我在HTTP.java.
在桌面上一切正常（不执行该请求，因为只有在 Android 上才需要）。
在Android中，没有那个http请求就可以正常工作。
在发出该 http 请求之后，所有其他请求都会在超时后失败并出现 UnknownHostException 错误，就好像他们不再有权访问 Internet 连接，即使它处于活动状态。同样在几分钟后和 onResume 之后，所有 http 请求都失败了。尽管该应用程序无法获得 http 响应，但 AdMob 广告出现在我的 App 中，所以我认为连接可能有效（或者 AdMob 库是否缓存了一些广告并在需要时显示它们？）。
通常，在这些情况下，它有时会再次起作用：
? 多次尝试后发现问题一出现，几乎每次，如果我激活飞行模式然后禁用它，数据连接被停用然后重新激活，并且App可以立即执行所有后续http请求，而不必在您的设备上执行任何其他操作，甚至无需重新打开应用程序。
.timeout(10000)我使用 10 秒的超时行中一样，服务器已将超时设置为 60 秒我正在测试具有平面 4G 连接和 wifi 的真实设备，并安装了“NetGuard - 无根防火墙” VPN 应用程序。
此 VPN 与所有其他应用程序都可以很好地运行，可能我的应用程序也是如此，但我不能排除这是问题所在，尽管我几乎不认为它是（我多年来一直没有问题地使用它）。
我的代码有问题吗？或者至少，我怎么知道这个错误的确切原因？
谢谢。
