The message **ENOTFOUND** is a DNS failure, which means the gateway can't resolve the host with the given hostname. You can find more information on DNS troubleshooting [in the Node.js documentation](https://nodejs.org/api/dns.html#dnslookuphostname-options-callback).

The **ENOTFOUND** message can happen for various reasons, such as:

1. The hostname is invalid.
2. Your network connection is faulty.
3. Your DNS server is faulty.
4. The DNS server that handles the domain name is faulty.
