Bad protocol version

[Alphapage]

Hello,

When updating axum-server from 0.6 to 0.7.1 in axum example-websockets-http2 (https://github.com/tokio-rs/axum/tree/main/examples/websockets-http2), I get a bad protocol version: native-tls error.
With the previous version, all is working as expected.

Related to : tokio-rs/axum#3068

Thank you in advance for your answers.

In the diff between 0.6 and 0.7.1 it looks like rustls default-features was turned off. TLSv1.2 is part of that default feature set, so in this version axum-server does not support TLSv1.2.

native-tls does not support TLSv1.3 so the client and server are speaking different protocols.

Look at my solution in seanmonstar/reqwest#2428 (reply in thread) for how to fix the issue based on your use case.
