遇到一个问题，即使我在AndroidManifest.xml中提供了Internet许可，使用https://github.com/square/okhttp-okhttp版本-3.12.1的应用程序也无法连接到域
但是，用户可以根据他们的评论在其设备上连接到Internet并使用其他应用。
目前，我无法重现该异常，因此，如果以前曾遇到此问题的任何人都可以帮助我更好地理解。
我现在不想升级库，因为我不想引入大的变化。

我通常使用Retrofit（使用Okhttp作为客户端）时遇到该错误，当设备没有任何互联网连接（WIFI或移动数据）或我的服务器端点关闭时，就会发生此错误。自己尝试！但是还有其他一些因素。例如runtime request permisions或network security config。
希望这会有所帮助，兄弟。>>
