    let res = reqwest::Client::builder()
        .danger_accept_invalid_certs(true)

        .unwrap()
        .get("https://api.kavenegar.com/v1")
        .send()
        .await?;

    println!("res: is {}", res.status());

    Ok(())
}

log result:

Error: reqwest::Error { kind: Request, url: "https://api.kavenegar.com/v1", source: hyper::Error(Connect, Custom { kind: Other, error: Os { code: 104, kind: ConnectionReset, message: "Connection reset by peer" } }) }

I don't have any problem when I use openssl or native-tls What's wrong?

I'm sorry, I don't know. Since you said it works with openssl, then it seems like a problem with rustls. It may be worth opening issue there.

@seanmonstar OK, I'm closing this now
