Firebase in production

I use firebase php-sdk for laravel. It works nice on my test site, on localhost, but on prod with same credentials doesn’t. Example: I validate same fcm token Firebase::messaging()->validateRegistrationTokens('fLaGUygupk9NkwcHkHyrsM:APA91bH7Y0QgNQ4XcHGWA8OC8i-FqBQ2nAKnv0P-BQhJp_kFPMsGOSTM8k8XJQawYCu9Anh24Yw5fN1aJoV8ATugdW-Epn-Lqow_39IahaXVL9Hhpqlkk_i1PHjgn0yRHOZPq6URI_7D') and on test site I have this

Array
(
    [valid] => Array
        (
            [0] => fLaGUygupk9NkwcHkHyrsM:APA91bH7Y0QgNQ4XcHGWA8OC8i-FqBQ2nAKnv0P-BQhJp_kFPMsGOSTM8k8XJQawYCu9Anh24Yw5fN1aJoV8ATugdW-Epn-Lqow_39IahaXVL9Hhpqlkk_i1PHjgn0yRHOZPq6URI_7D
        )

    [unknown] => Array
        (
        )

    [invalid] => Array
        (
        )

)

but on prod – this

Array
(
    [valid] => Array
        (
        )

    [unknown] => Array
        (
        )

    [invalid] => Array
        (
        )

)

I create new key, new tokens but result is the same
