fails on second call

[AidasK]

>>> app('pubsub')->publish('channel_name', 'messagesr');                                
=> null
>>> app('pubsub')->publish('channel_name', 'messagesr');
Google\Cloud\Core\Exception\ServiceException with message 'cURL error 35: Bulk data encryption algorithm failed in selected cipher suite. (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)'

On the first call channel_name is created (I can see it in the console), but on the second one it fails.
