React Native Android：请求适用于 android 模拟器，但不适用于 Play Store 构建

我有一个 React Native 应用程序，它正在发出一个简单的登录请求。此请求在 ios 模拟器中有效，并且在我将构建安装到我的设备上时有效。当我从 Play 商店下载应用程序时它不起作用。

我已尝试以下操作： 我已重新安装并安装了该应用程序。查看生产日志，我没有看到请求到达 rails 服务器的任何记录。我一直在使用 bugsnag 日志记录。

这是请求：

sendLoginEmail = (isResend) => {
    bugsnag.notify(new Error(`1: ${this.state.email}`))
    enterEmail(this.state.email).then(response => {
      console.log("sle response!")
      console.log(response)
      bugsnag.notify(new Error(`2: ${this.state.email}`))
      bugsnag.notify(new Error(JSON.stringify(response)))
      if (response.status === 200) {
        this.setState({isEmail: false, isLoading: false, warningMessage: isResend ? "Email resent" : null});
      } else {
        this.setState({isLoading: false, warningMessage: "Something went wrong. Please try again."})
      }
    }).catch(response => {
      bugsnag.notify(new Error(JSON.stringify(response)))
    })
  }

enterEmail 看起来像这样：

export const enterEmail = (email) => {
  return fetch(`${host}/v2/users`, {
    method: 'POST',
    headers: {
      Accept: 'application/json',
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      user: {
        email
      }
    })
  })
}

Bugsnag 记录第一个错误 ( bugsnag.notify(new Error(1: ${this.state.email} ))) 并捕获抛出的错误并记录响应。该响应显示在index.android.bundle下列行：new TypeError('Network request failed')。

这是我的 nginx.error.logs：

我怀疑我的 nginx 配置有问题，但我不知道它是什么。

我猜生产/调试 android 版本在某种程度上是不同的，这可以解释为什么当从 android studio 安装时请求在我的设备上工作，而不是从 Play 商店安装。我不知道这有什么区别。

谢谢。
