Hi all,

I get a cryptic error:

Uncaught Error: write EPROTO 4478952896:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:../deps/openssl/openssl/ssl/record/ssl3_record.c:252:

      at WriteWrap.onWriteComplete [as oncomplete] (internal/stream_base_commons.js:66:16)

Following is almost a copy of your documentation:

NODE_EXTRA_CA_CERTS: /Users/dmitrymedvedev/Library/Application Support/mkcert/rootCA.pem

const CA_PATH = path.resolve('./certs');
const httpsConfig = {
  get cert() {
    return readFileSync(path.resolve(path.join(CA_PATH, 'localhost+2.pem')));
  },
  get key() {
    return readFileSync(
      path.resolve(path.join(CA_PATH, 'localhost+2-key.pem')),
    );
  },
};

// ...

const httpsServer = new https.createServer(httpsConfig);

this.wss = new WebSocket.Server(
  Object.assign(
    {},
    this.settings.wss,
    { server: httpsServer },
  ),
);

This sounds like a TLS stack issue rather than a mkcert issue, but if you found a solution it might be useful to leave a pointer here for the next person to encounter it.
