mkcert HTTPS certificate (with nestjs local server) is working on local machine only

I have nestjs server running locally that I set up to handle HTTPS requests via mkcert.my main.ts file looks like this:

async function bootstrap() {  const httpsOptions = {    key: fs.readFileSync('./cert/localhost+1-key.pem'),       cert: fs.readFileSync('./cert/localhost+1.pem'),  };  const app = await NestFactory.create(AppModule, { cors: true, httpsOptions });  app.useGlobalPipes(    new ValidationPipe({      whitelist: true,      transformOptions: { enableImplicitConversion: true },    }),  );  app.use(json({ limit: '50mb' }));  app.use(urlencoded({ extended: true, limit: '50mb' }));  await app.listen(3333);}bootstrap();

I have a pwa (react - vite - pwa) app deployed on netlify. If I open the app locally (same machine I have the running server) and send https request to my local nestjs server I get a normal response. However, if I open the same app on a different machine or mobile device, I get (failed)net::ERR_CERT_AUTHORITY_INVALID.

Is there any way to configure nestjs server to receive https requests from any machine/device with mkcert or is it a wrong tool for the task?
