【问题描述】：
我遇到了在 HTTP.java 中完成的 http 请求的问题。
在桌面上一切正常（该请求未执行，因为它仅在 Android 上是必需的）。
在 Android 中，无需该 http 请求即可正常工作。
发出该 http 请求后，所有其他请求都会在超时后失败并出现 UnknownHostException 错误，就好像它们不再能够访问 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。 虽然应用无法获得 http 响应，但 AdMob 广告出现在我的应用中，所以我认为可能连接有效（或者 AdMob 库是否缓存了一些广告并在需要时显示它们？）。
通常，在这些情况下有时它会再次起作用：
- 从 Android Studio 卸载并重新安装应用程序
- 关闭应用，等待几分钟后重新打开
- 从设备中清除应用数据
- 等待未定义的时间
❗经过多次尝试我发现问题一出现，几乎每次，如果我启动飞行模式然后禁用它，数据连接被停用然后重新激活，应用程序可以立即执行所有后续的http请求，而无需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。
- 在 1GB fibra 网络上使用 wifi 测试：同样的错误
- 我检查了连接：它很稳定，在 wifi 和 SIM 卡中
- 在清单中有使用互联网的许可（否则它永远不会起作用）
- 同时，桌面上的同一个 App 运行完美，速度最快，不到 1 秒就接收到 http 响应，所以服务器不是问题
- 我还使用 url https://www.google.it 进行了测试：同样的错误，相同的 url 可以在不到 1 秒的时间内通过浏览器在设备中访问
- 在
.timeout(10000)行中，我使用的是 10 秒的超时，服务器已将超时设置为 60 秒 - 检查了https://www.ssllabs.com/ssltest 的服务器 SSL“质量”：在“总体评级”中获得“A”
- 直接通过 Vodafone 运营商完成 SIM“重启”
我正在使用纯 4G 连接和 wifi 的真实设备上进行测试，并安装了“NetGuard - 无根防火墙”VPN 应用程序。
这个 VPN 可以很好地与所有其他应用程序配合使用，可能我的应用程序也是如此，但我不能排除这是问题所在，尽管我几乎不认为这是问题（我多年来一直在使用它，没有任何问题）。
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。

我刚刚通过 Vodafone 运营商直接执行 SIM“重启”，所以现在我应该排除 SIM 问题。

我的解决方案：
卸载 VPN 应用。
这是一个如此简单的解决方案...我不会想到这是 VPN 的应用程序的错，我认为它已经使用了 3 年多了...
如果这不是问题所在，您的建议肯定会很有帮助，而且可能是决定性的，谢谢大家！ （不幸的是，我不能故意将赏金奖励给多个用户，但我可以投票给你的答案）
【问题讨论】：
-
您是否在清单中声明了
android.permission.INTERNET？<uses-permission android:name="android.permission.INTERNET"/> -
@AlwaysLearning 当然。正如我所说，问题并不总是发生，无需对代码进行任何更改。有时一切正常，有时会发生错误
-
我会根据日志再次检查您是否拥有该权限。如果没有，我建议添加它并查看是否可以解决问题。
-
我刚刚看到在清单中设置了权限，并且还按照设备上的应用程序设置中的指示授予了权限
-
好的，谢谢您的确认。
enterpriseCtrl是什么？那似乎不是Android构造？另外，为什么 netd 调用它？它返回 0 的事实意味着您没有使用可以解释您的问题的网络。
