android - 如何解决 "Token retrieval failed: AUTHENTICATION_FAILED"？

Question

我已经实现了所有文档，但仍然出现此错误。

This is my log:
W/FirebaseMessagingPlugin(29848): getToken, error fetching instanceID: 
W/FirebaseMessagingPlugin(29848): java.io.IOException: AUTHENTICATION_FAILED
W/FirebaseMessagingPlugin(29848):   at com.google.firebase.iid.zzs.zza(Unknown Source:71)

我已经经历了很多可用的选项，但仍然无法理解这个问题......

这里是项目gradle:

dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.2.0'
    }

这是应用程序 gradle:

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

应用插件:'com.google.gms.google-services'

没有生成 token ...每次运行应用程序时都会显示上述错误。 我试过清理等等……有什么帮助吗？？

我已通过将网络适配器的 IPV4 DNS 从自动更改为 8.8.8.8(Google 的公共(public) DNS)来解决此问题
