Fix Connection Refused Error in Django

What Is the Connection Refused Error?

Running into Connection Refused while working with Django? This guide walks you through the root cause and a clean solution.

Why It Happens

This happens when the target server isn't running, the port is wrong, or a firewall is blocking the connection.

The Fix

import requests
from requests.adapters import HTTPAdapter
from urllib3.util.retry import Retry

session = requests.Session()
retries = Retry(total=3, backoff_factor=0.5)
session.mount('http://', HTTPAdapter(max_retries=retries))

try:
    response = session.get('http://localhost:8000/api/data')
except requests.ConnectionError:
    print("Server unreachable — verify it's running")

Environment Checklist

Before assuming the code is wrong, run through this checklist for your Django project: verify all environment variables are set correctly, confirm your dependency versions match across environments, check that network connectivity to external services is working, and ensure file permissions are correct. Many instances of Connection Refused stem from environmental issues rather than code bugs.
