How to resolve the certificate verification failed error in Linux?

help

Hi, I'm working on web sockets for which I used the "tungstenite" crate. While working on windows, the application was working fine, but when I tried the same in Linux machine I was getting "certificate verify failed" error.

Code:

use tauri::Manager;
use tungstenite::{connect, Message};
use url::Url;
use std::sync::{Mutex};

fn main() {
    let (socket, _response) = connect(Url::parse("wss://127.0.0.1:8080/ws").unwrap()).expect("Failed to connect");       
    println!("WebSocket Connection Established !! \n");          
    tauri::Builder::default()  
    .setup(move |app|{
      let app_ = app.handle();
        let stream = Mutex::new(socket);      
        app.listen_global("request", move |_handler| {  
        let mut data = stream.lock().unwrap();
        data.write_message(Message::Text(r#"{
            "type": "config"
        }"#.to_string()+"\n")).unwrap();

    let msg = data.read_message().expect("Error reading message");
    let message = msg.to_string();
    let parsed: serde_json::Value = serde_json::from_str(&message).expect("Can't parse to JSON");
    app_.emit_all("socket-response", parsed).unwrap();
      });
    Ok(())
    })
    .run(tauri::generate_context!())
    .expect("error while running tauri application");
}

Error:

thread 'main' panicked at 'Failed to connect: Tls(Native(Ssl(Error {​​​​​ code: ErrorCode(1), cause: Some(Ssl(ErrorStack([Error {​​​​​ code: 337047686, library: "SSL routines", function: "tls_process_server_certificate", reason: "certificate verify failed", file: "../ssl/statem/statem_clnt.c", line: 1913 }​​​​​]))) }​​​​​, X509VerifyResult {​​​​​ code: 20, error: "unable to get local issuer certificate" }​​​​​)))', src/main.rs:8:87
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Can someone let me know how to solve this error?
