My tokio won't send data on Ubuntu

[fu050409]

I have a strange problem, I made a custom TCP based end-to-end encryption protocol, however when using stream.write_all and stream.write on Ubuntu, the client didn't receive any data, but the connection was normal and the server was able to receive data normally.

My code passed the test locally on my computer (I have Windows) and I tested it locally on my Ubuntu host without any anomalies. I tried running my code on a Windows remote host and I was equally successful (remote access and local access).

For what it's worth, I also wrote a Python implementation for it, and it works fine on my Ubuntu server. It interfaces correctly with the Rust client.

I'm not sure why this is, I'm using the latest version of Rust and tokio at the moment.

Forgive me if I asked a stupid question.

You have not really provided very much information. Perhaps you need to flush after writing?

[fu050409]

Yes, I tried stream.flush, but it still not work.

[fu050409]

I tried this approach and even if I do a flush after every write method call it doesn't work:

match stream.write_all(&data).await {
        Ok(_) => {
            match stream.flush().await {
                Ok(_) => {}
                Err(e) => {
                    return Err(OblivionException::UnsupportedMethod {
                        error: e.to_string(),
                    });
                }
            };
        }
        Err(e) => {
            return Err(OblivionException::UnsupportedMethod {
                error: e.to_string(),
        });
    }
};

My Ubuntu is Ubuntu 22.04.3 LTS (GNU/Linux 5.15.0-84-generic x86_64)

If you need any more information feel free to let me know, I've been confused by this for a long time

[fu050409]

I've been trying for a long time and I think it might be a server operator issue. I apologize for the disturbance.
