DTLS ServerKeyExchange failure

Could anyone help me out here? I am attempting to set up connectivity of a WebRTC-rs client DataChannel with https://github.com/naia-rs/naia-socket ... and it appears that the DTLS handshake is failing on the ServerKeyExchange message given, exactly here: https://github.com/webrtc-rs/dtls/blob/main/src/handshake/handshake_message_server_key_exchange.rs#L114 The message indicates that the incoming signature will be something like ~19000 bytes, but the incoming message size is only ~300 bytes ... curious.

The failing message is created/written by an openssl::SslAcceptor which is created here: https://github.com/kyren/webrtc-unreliable/blob/master/src/crypto.rs#L56

I have created an example repo to demonstrate this behavior here: https://github.com/naia-rs/naia-socket-webrtc-rs-example, you should be able to reproduce this pretty quite using this repo.

I suspect a DTLS version mismatch here? Does anyone know how I can check the version of DTLS being used to read/write messages in both openssl & webrtc-rs/dtls?

Thank you so much for any help!

is there support for drat DTLS-1.3?

is there support for draft DTLS-1.3

[DTLS] handle multiple connections for DTLS server

Currently DTLS server can't handle multiple connections.

A listener interface should be implemented for DTLSConn.

Checking in on the status of this crate

Thanks for making the effort to port Pion over to Rust 🙏 , it is a massive undertaking. I've been playing around with this crate and ran into an issue with the handshake (can't get past flight 1 as a client), and wanted to rule out any library issues. Have you been able to get this crate working with a handshake from a browser? If so, was it as a client, server, or both (also, which browser)? Would you mind sharing any code you have that you use to validate features (or links to repos that use this crate)? It would be greatly appreciated. Thank you!
