MissingConnectionUpgrade when connecting from wss client

[trampster]

When I try to do it with the following:

tokio_tungstenite::connect_async_with_config(
        format!("{}websocket?token={}",
        wss_target_url, subscribe_response.token),
        Some(tokio_tungstenite::tungstenite::protocol::WebSocketConfig {
            max_send_queue: Some(target_cnf.performance.websocket_send_queue_limit),
            max_message_size: None, // unlimited
            max_frame_size: None,  // unlimited
        })
    )
    .await
    .with_context(|| format!("failure to connect to"))?;

With this in my cargo.toml

tokio-tungstenite = { version = "0.11.0", features = ["tls"] }

Then I get this error (serverside):

warp::filters::trace: unable to serve request (client error) status=400 error Rejection([MissingConnectionUpgrade, MethodNotAllowed, MethodNotAllowed])

Googling indicates that there should be a upgrade header telling the server to upgrade the https connection to the websocket. But for some reason it is missing.

You are using the tls feature, but there is no such feature, try to use native-tls or rustls-tls-webpki-roots or other TLS features (depending on your requirements) and I think it would allow you to get the behavior you expect 😉

See Features section for more details.

With: tokio-tungstenite = { version = "0.11.0", features = ["native-tls"] }

I get "URL error: TLS support not compiled in"

Ah sorry, I did not notice you used the version 0.11.0, it's a very old version. The current version is 0.17.1, could you try with it?

NB: Version 0.11.0 should work with tls feature though. Not sure why it fails. Do you have a SSCCE that could be used to verify the issue?
