 * When making an HTTPS connection through an HTTP proxy, the proxy may issue an authentication challenge. OkHttp will call the proxy [authenticator](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-authenticator/) and try again.
 * When making TLS connections with multiple [connection specs](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-connection-spec/), these are attempted in sequence until the TLS handshake succeeds.

And then they can try again knowing that it's probably something more similar to `stanleyjobsox` than to `johndoe`.

Envoy has stopped requested them; if there are no subscriptions they update will be ignored. If Envoy later watches these certificates again,
a new one will be generated on demand.
