Run examples code and generate pem

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes -subj "/CN=localhost"

use this pems run this example:

Hi,

I know this issue is open for long but I wanted to serve a solution.

You have to trust the certificate that server provides. For this you should enable tls for client too with the same certificate the server has. Here is an example:

let server = Server::builder()
        .with_io("127.0.0.1:4585")
        .unwrap()
        .with_tls((
            Path::new("certificates/cert.pem"),
            Path::new("certificates/key.pem"),
        ))
        .unwrap()
        .start()
        .unwrap();

let client = Client::builder()
        .with_io("127.0.0.1:0")
        .unwrap()
        .with_tls(Path::new("certificates/cert.pem"))
        .unwrap()
        .start()
        .unwrap();

Be careful I gave same certificate for client and server but only server has private key.
