How can push notification be sent on safari OS X?

Question

PHP

I've had a problem for probably more than 4 days - I just can't send push to safari. deviceToken - I received from the site.
Checking the certificate:

openssl s_client -connect gateway.push.apple.com:2195 -cert apns-dev.pem -key apns-dev.pem

There is quite a lot of information there, but the main thing is the server - Entrust and Verify return code: 0 (ok) - in my opinion everything is fine with the certificate.
As for the code - I tried these libraries:
https://github.com/jwage/php-apns
https://github.com/richsage/RMSPushNotificationsBundle
and tried without libraries via stream_context_create() and stream_socket_client()
I probably won't give the code it is quite simple - it was taken from git'a from the above libraries and worked out without errors.
As for generating a certificate, I tried to generate it in two different ways:
stackoverflow.com/questions/6372308/apns-ssl-gatew...
and more sophisticated

I don't know where to look for the error and why I can't get a push. My site is in Safari's Notifications list. Selinux is disabled on the server.
Many thanks to everyone for any advice.
