Enable DTLS encryption
Configure your Relay client to use Datagram Transport Layer Security for encrypted connections.

Note
Enabling DTLS encryption only enables encryption of message. Other Relay behavior, such as timeouts, remains the same.
connectionTypedtlsWarning
Secure connections using DTLS are only available with Unity Editor versions 2020.3 (starting at 2020.3.34), 2022.1, and above.
Note
Players joining the host player can use a different connection type than the host player. However, most gaming platforms required encrypted connections.
