Blynk + raspberry pi project 8441

I have problem. My project can’t connect blynk server please help me step by step.

syscall: ‘connect’,
address: ‘’,
port: 8441 }

step 1. search for ECONNREFUSED in the forums.
here is a link that might help.
each one of these in the results were solved the same way.

you could add 8441 to the search query if you have bad luck with the link i gave.

step 2. Im not sure… usually after people search the forums, their next questions are about code and code corrections and they never ask again about connectivity methods.
