Can't get SSL/TLS to work

[MatthewFrisky]

I am using the library in react-native with SSL/TLS like so:

(async () => {
    try {
      // Paths to your certificate files
      const certPath =
        'client.crt';
      const keyPath =
        'client.key';
      const caPath =
        'ca-root-cert.der';

      const clientCert = await readFile(certPath);
      const clientKey = await readFile(keyPath);

      // Read DER file as a Buffer
      const caDer = await readFile(caPath, 'base64'); // Read DER file as base64

      // Configuration
      const tlsOptions = {
        caDer: Buffer.from(caDer),
        cert: clientCert,
        key: clientKey,
      };

      const options: ConnectionOptions = {
        clientId: 'myClientId',
        cleanSession: true,
        keepAlive: 60,
        timeout: 60,
        maxInFlightMessages: 1,
        autoReconnect: true,
        username: 'user',
        password: 'pass',
        tls: tlsOptions,
        allowUntrustedCA: true,
        enableSsl: true,
        protocol: 'mqtts',
      };

      MqttClient.connect('mqtts://127.0.0.1:8883', options)
        .then(() => console.log('Connected'))
        .catch(error => console.error('Connection failed: ', error));
    } catch (error) {
      console.error('Error loading certificates:', error);
    }
  })();

My Mosquitto config is:

listener 8883
cafile ca-root-cert.crt
certfile server.crt
keyfile server.key
require_certificate true
allow_anonymous true

But I am just getting a protocl error from Mosquitto when trying to connect.

I have tested the certificates using mosquitto_sub and they are working there and also tested that I am correctly reading in the certificate files from the directories so I am not sure what the issue is.

Also the connection works fine if I don't use TLS/SSL and it even works using username/password.

If you have any insight please let me know.

Sorry, I am currently using iOS for testing.

@MatthewFrisky I find it hard to have an environment to recreate this. Can you give me code and environment to recreate this?
