TlsHandshakeFailure

[lynn2910]

Hello, i have an error when connecting to a secure websocket (url: wss://gateway.discord.gg)

Error:

thread '<unnamed>' panicked at 'called `Result::unwrap()` on an `Err` value: Other(TlsHandshakeFailure)', src/workers/ws.rs:45:14

I declare the client with

        let client = ClientBuilder::new(&*url)
            .unwrap()
            .connect(None)
            .unwrap();

It seems like connecting to a wss throw this error.
Perhaps, when i try using "ws://echo.websocket.org", i get:

thread '<unnamed>' panicked at 'called `Result::unwrap()` on an `Err` value: Other(StatusCodeError(Ok))', src/workers/ws.rs:47:14

(trace:)

But the websocket doesn't initialize itself when connecting to a wss

[vi]

ws://echo.websocket.org

No longer works. You can use ws://ws.vi-server.org/mirror instead.

What is the reason of using websocket instead of recommended alternative tungstenite?

This address works properly, but how can I connect to wss since I have the handshake failure ?

[lynn2910]

What is the reason of using websocket instead of recommended alternative tungstenite?

Because, I use this in the crate mlua, but the Tokio runtime can't be used a athis context.
That's why I need a websocket client that is not async

Tokio runtime can't be used a athis context

I don't remember tungstenite (unlike tokio-tungstenite or async-tungstenite) to be dependent on Tokio.

Does tungstenite::client_tls match your needs?
