Hi there,  
since march 2017, I get a “APNS Connection Failed: 0” when I try to send a notification to my users. Certificates are ok, I tried through [http://www.pushtry.com](http://www.pushtry.com).  
Did someone faced to the same problem ?  
Any idea welcome.  
Best regards.

Thanks for your answer shogunkaramazov.  
I forgot to say that it worked perfectly for years since 2014. Nothing has changed except updating the certificates. Do you have another idea ?
