我试图按照这个链接Could not GET 'play-services-location/maven-metadata.xml'. Received status code 502 from server: Bad Gateway的步骤，但我仍然得到错误，有没有办法解决这种情况。我从昨天开始就一直在尝试解决这个问题，但还是得到了错误。这是我的android/build.gradle

buildscript {
    ext.kotlin_version = '1.3.61'
    repositories {
        google()
        // jcenter()
        mavenCentral()
    }

    dependencies {
        // classpath 'com.android.tools.build:gradle:3.5.0'
        // classpath 'com.android.tools.build:gradle:3.4.2'
        classpath "com.android.tools.build:gradle:4.2.0"
        
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.3'
    }
}

allprojects {
    repositories {
        google()
        // jcenter()
        mavenCentral()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
    
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
