Steps:
Opening server tls socket (tls::socket)
Client connects and tls1.3 handshake completes successfully
Data exchanged
Server tls socket closed (close)
close_notify received from client
Server sent [ACK]
Client sent [FIN, ACK]
Server sent [ACK]
Server sent [RST, ACK]

Questions:
1) no response to close_notify sent by server? expected?
2) if disabled tls1.3 (i.e. set to false), then also no response to close_notify sent by server? expected?
3) how to fix so that server will respond to client's close_notify
