Catch if Rabbit server is down

How can I check if the RabbitMQ server is down? In the client, I shutdown RabbitMQ local server to check if I can catch the error but all I receive is:

(node:90094) UnhandledPromiseRejectionWarning: Error: connect ECONNREFUSED 127.0.0.1:5672

This happens as a response to

    this.client = new ClientRMQ({
      url: `${process.env.CLOUDAMQP_URL}`,
      queue: 'ampanova_mails',
      queueOptions: { durable: false }
    })
