Solutions to ECONNREFUSED Nodejs + Nginx Server Error

Resolving the ECONNREFUSED Nodejs + Nginx server error can be challenging, as it requires a step-by-step approach. Here are some viable solutions to resolve the ECONNREFUSED error:

1. Check your server’s status

The first thing to do when faced with the ECONNREFUSED error is to verify the status of the server running Nodejs. Ensure that the server is running without any issues.
