Failed to start the resumable upload - php

Question

Api Version 0.6.2
I was following this answer:
Post large video to youtube via google php client api v3
I'm getting
Failed to start the resumable upload
500 Internal Server Error - Google_Exception
Stack Trace

return $location;
}
throw new Google_Exception("Failed to start the resumable upload");
}
}

while (!$status && !feof($handle))
{
$chunk = fread($handle, $chunkSizeBytes);
$uploadStatus = $media->nextChunk($result, $chunk);
var_dump($uploadStatus);
}
When trying to post a nonresumable upload I'm getting a 400 Bad Request error.
Error Message
Error calling POST https://www.googleapis.com/youtube/v3/videos?part=status%2Csnippet&key=replacedkeystring: (400) Bad Request

I have authenticated a few hours ago. I saw that the token lifetime was 3600 (1h).
This is also done locally
Could this be the reason or what could be the reason?
Any help appreciated.
