Cloudflare TLS issue - Disabling SSL Check not working?

[rohitcoder]

Hi There, I'm getting below erorr from reqwest, i tried to solve it with danger_accept_invalid_certs(true) but still the same issue. I am having this issue on Ubuntu EC2 Instance, any help or guidance please? I also checked rust discussion forum https://users.rust-lang.org/t/reqwest-tls-error-with-use-native-tls/49627 but still i wasn't able to solve this issue. BTW, I'm using Cloudflare's free SSL

thread 'tokio-runtime-worker' panicked at 'called `Result::unwrap()` on an `Err` value: reqwest::Error { kind: Request, url: Url { scheme: "https", cannot_be_a_base: false, username: "", password: None, host: Some(Domain("api.domain.com")), port: None, path: "/graphql", query: None, fragment: None }, source: hyper::Error(Connect, Ssl(Error { code: ErrorCode(5), cause: None }, X509VerifyResult { code: 0, error: "ok" })) }', src/internal/common.rs:272:10

My Code is like this

pub async fn graphql_query(
    url: &str,
    query: &str,
    variables: &Value,
    headers: &reqwest::header::HeaderMap,
) -> Result<reqwest::Response, reqwest::Error> {
    let client = Client::builder().danger_accept_invalid_certs(true).build().unwrap();
    let request_body = json!({
        "query": query,
        "variables": variables,
    });
    let resp = client.post(url).headers(headers.clone()).json(&request_body).send();
    match resp.await {
        Ok(r) => Ok(r),
        Err(e) => Err(e),
    }
}
