Packet loss, in particular loss of a Handshake packet from the server, can cause a situation in which the server cannot send when the client has no data to send and the anti-amplification limit is reached. In order to avoid this causing a -handshake deadlock, clients SHOULD send a packet upon a crypto retransmission -timeout, as described in {{QUIC-RECOVERY}}.
