PHP Google translate service v3 - connection problem - guzzlehttp - php

Question

The code in PHP:
<?php
require 'C:\inetpub\wwwroot\Imzo.be\vendor\autoload.php';
putenv('GOOGLE_APPLICATION_CREDENTIALS=C:\inetpub\wwwroot\Imzo.be\secret\central-eon-267809-2d6dc3c388dc.json');
use Google\Cloud\Translate\V3\TranslationServiceClient;
function translate($text, $to){
$projectId = "central-eon-267809";
$translationClient = new TranslationServiceClient();
$string = $text;
$string = strip_tags(htmlspecialchars_decode($string));
$string = utf8_encode($string);
$content = [$string];
$targetLanguage = $to;
$response = $translationClient->translateText(
$content,
$targetLanguage,
TranslationServiceClient::locationName($projectId, 'global')
);
foreach ($response->getTranslations() as $key => $translation) {
$separator = $key === 2
? '!'
: ', ';
return $translation->getTranslatedText(); //. $separator;
}
}
?>
The Json-file (i'll make a new one when solved):

The error:

Does anyone know what is wrong in this?
I think everything is configured correctly in the Google Cloud.
It might be a problem with the auth_uri or token_uri.
Please help.
