Unable to connect using SSL (Unknown error) to RabbitMQ server via PHP AMQP

[pit3rek]

PHP AMQPLib version 2.12.1
RabbitMQ 3.8.9
Erlang 23.1.4

RabbitMQ server config:

[
  {ssl, [{versions, ['tlsv1','tlsv1.2']}]},
  {rabbit, [
     {log_levels, [{connection, error}]},
     {ssl_listeners, [5671]},
     {ssl_options, [{cacertfile,"/etc/rabbitmq/ssl/ssl4/result/ca_certificate.pem"},
                    {certfile,"/etc/rabbitmq/ssl/ssl4/result/server_certificate.pem"},
                    {keyfile,"/etc/rabbitmq/ssl/ssl4/result/server_key.pem"},
                    {versions, ['tlsv1','tlsv1.2']},
                    {verify, verify_peer},
                    {fail_if_no_peer_cert, false}]}
   ]}
].

When I try connect via openssl everything is ok, but when I'm connecting via PHP AMQP I'm getting an error:

PHP Fatal error: Uncaught PhpAmqpLib\Exception\AMQPIOException: stream_socket_client(): unable to connect to ssl://fend01-TEST:5671 (Unknown error) in /var/www/html/rabbitmq/vendor/php-amqplib/php-amqplib/PhpAmqpLib/Wire/IO/StreamIO.php:110

ssl_opts are:

 'capath' => '/etc/rabbitmq/ssl/ssl4/result/',

'cafile' => '/etc/rabbitmq/ssl/ssl4/result/ca_certificate.pem',
'local_cert' => '/etc/rabbitmq/ssl/ssl4/result/client_certificate.pem',
'local_pk' => '/etc/rabbitmq/ssl/ssl4/result/client_key.pem',
'ssl_version' => 'tlsv1',
'verify_peer' => true,
'verify_peer_name' => false

$connection = new AMQPSSLConnection('fend01-TEST',5671,'login',password,'vhost', $ssl_opts);

It's working. Stupid mistake. Wrong permissions to /etc/rabbitmq/ssl directory.
