QUIC is not supported

HTTP/3 is supported

HTTP/3 Check failed to establish a QUIC connection for all attempts made with the given endpoint. See the connection errors below for more information.

Attempted 2 connection(s).
Received packets for 1 connection(s).
Successful handshake for 1 connection(s).

QUIC Versions

These are the QUIC versions supported by this QUIC endpoint.

Connection ID

Connection ID

This unique identifier for a QUIC connection is used to ensure that changes to an endpoint's lower network layer address (UDP/IP) does not affect the delivery of the QUIC connection's packets.

This tool attempts two connections to test the server's 0-RTT capabilities. During the first connection, the client receives important handshake material from the server. With 0-RTT, the client can start to send data immediately if it uses this handshake material when it creates the second connection.

Packet RX

Packet RX

This value represents the time between the first packet sent and the first packet received (measured in milliseconds).

 Handshake Done

Handshake Done

This value represents the time between when the first packet is sent and when the handshake is completed (measured in milliseconds).

Take notice of the difference in this metric between the first connection and the second connection. Using 0-RTT, future connections (i.e. the second connection) can complete the handshake much faster than the original connection.
