Error after PHP update

Hello, I’m facing this error after upgrade PHP to version 7.0.

While trying to spawn a call to the WP-Cron system, the following error occurred:
stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages: error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure stream_socket_client(): Failed to enable crypto stream_socket_client(): unable to connect to ssl://www.mywebsiteurl.com:443 (Unknown error)

Can anyone help me?

Thanks
