Sometimes my script, that sends push notifications crashes with error:
Warning: stream_socket_client() [function.stream-socket-client]: SSL
operation failed with code 1. OpenSSL Error messages:
error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake
failure
And sometimes everything is ok. I think this is not connected with certs or code. Cause I’m sending the same messages to the same devices and use the same algorithm. Any ideas ?
Regarding your question in the title – no, there’s no guarantee that notifications will arrive.
