我正在尝试运行我的 react-native 应用程序，我在 android 模拟器和我的手机 HUAWEI Y3II 上运行它，并且发生了同样的事情。几天前我正在努力解决它，但突然这个错误不断出现：
Could not load exp://*myip*:19000 network response timed out

终端日志显示：

Fetching the user profile failed

aTrying to open the project on Android...

我尝试将环境变量 REACT_NATIVE_PACKAGER_HOSTNAME 设置为我的 IP 地址，我尝试关闭防火墙，我确保防火墙中允许端口，我尝试将我的网络从公共网络更改为私有网络。这是我的 package.json 文件：
