Inconsistent error occured [getaddrinfo ENOTFOUND]

hi there!
I’m using slack webhook for payment alarm in my service.
However, inconsistent errors have been occurring for some time.

I’m using meteor v1.8 & HTTP module in “meteor/http”

for example,
When 10 payments occur, a slack alarm is not sent for approximately 1 case.

I don’t know why this error occured
I want to know where to doubt and how to approach it.

facing this error,

{ Error: getaddrinfo ENOTFOUND
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:56:26)
  errno: 'ENOTFOUND',
  code: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: '',
  host: '',
  port: 443 }

It sounds like your networking has some issue. Maybe you can try to change the DNS server or add the ip address of to hosts file.
