That error means your app tried to open an HTTPS connection to 57.153.227.198 on port 443, but the connection was refused before it could be established. In plain terms, nothing accepted the request at that IP/port, or something on the network blocked it.

What it usually means

ECONNREFUSED is a TCP-level failure, not an application-level response. The server, firewall, VPN, proxy, or local network path is rejecting the connection attempt, so the client never reaches the point of getting an HTTP status code.

Common causes

  • The service at that IP is down or not listening on port 443.
  • The IP address or hostname is wrong, or the app is using the wrong port.
  • A firewall, VPN, ISP rule, or security policy is blocking the connection.
  • The endpoint is private or restricted to certain networks.

What to check

  1. Confirm the target is actually supposed to be reachable on 443.
  1. Verify the IP address and port in your config or environment variables.
  1. Check whether a proxy, VPN, or firewall is interfering.
  1. Make sure the remote service is running and listening.
  1. If this is your own server, inspect logs and restart the service if needed.

In one sentence

It means the network connection was actively refused at 57.153.227.198:443, so the problem is usually a down service, wrong address/port, or a firewall/network block.

TL;DR: connect ECONNREFUSED 57.153.227.198:443 means the HTTPS connection was rejected before it could connect, so focus on the server being up, the IP/port being correct, and any firewall or VPN issues.
