Raspberry pi Error: connect ECONNREFUSED

Error: connect ECONNREFUSED
at Object._errnoException (util.js:1022:11)
at _exceptionWithHostPort (util.js:1044:20)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1198:14)
syscall: ‘connect’,
address: ‘’,
port: 8441 }

i tried everything even changed the port. i need help. step by step solution would be helpful. i did not face this problem a week ago.

How about a search suggestion :stuck_out_tongue: such as searching just the last day or two of similar issues due to using old ports like 8441.

Keeping up with the announcements is also highly recommended


i do not know how to change the port to 443. please explain the steps.

I guess that depends on the library used… WiringPi, NodeJS or Python
