Android Crashlytics InterruptedIOException timeout

I added Crashlytics to project build.gradle:

classpath 'com.google.gms:google-services:4.3.3'
classpath 'com.google.firebase:firebase-crashlytics-gradle:2.2.0'

and to app build.gradle:

dependencies {
    implementation 'com.google.firebase:firebase-crashlytics:17.1.1'
    implementation 'com.google.firebase:firebase-analytics-ktx:17.4.4'
}

apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.google.firebase.crashlytics'

Now i have this error after launching my app:

E/FirebaseCrashlytics: Settings request failed.

What i've tried:

• rebuilding the project
• invalidating Android Studio caches
• downloading and updating google-services.json
• adding ext.enableCrashlytics = true to build.gradle

But i have no result
