Error message containing
ECONNREFUSED represents a connection problem. This error is rare, and we have taken measures such as increasing server scalability.
If this error
ECONNREFUSED is occurring frequently, End-user should implement 2-3 retries in code because connection error may also be caused by your ISP, by temporary issues with routers and many other things. TCP/IP connection is not guaranteed by the design, so any temporary issues with the local ISP, routers, DNS providers may affect the connectivity. Zapier and Integromat have built-in retries.
