This error isn't related and is mostly a lower level network error: "cURL error 35: OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to fcm.googleapis.com:443"

From cURL's errors, this is defined as:

A problem occurred somewhere in the SSL/TLS handshake. You really want the error buffer and read the message there as it pinpoints the problem slightly more. Could be certificates (file formats, paths, permissions), passwords, and others.

If it's a one off, you can ignore it. If it happens with every time a push is triggered, then it may indicate that there's something involved in your system that is interfering with this SSL connection.
