Python Requests - Name or Service Not Known Error

If you are using Python requests library to make HTTP requests, and you encounter the "Name or Service Not Known" error, it means that your program is unable to resolve the hostname of the URL you are trying to access.

Causes of Name or Service Not Known Error

  • Incorrect URL: Make sure that the URL you are trying to access is correct and valid.
  • Network connectivity issues: Check your internet connection and try accessing the URL from your web browser to see if it loads properly.
  • Firewall or proxy settings: If you are behind a firewall or using a proxy server, your program may not be able to resolve the hostname. You may need to configure your firewall or proxy settings to allow access to the URL.
  • DNS resolution issues: If the DNS server that your program is using is down or not responding, it won't be able to resolve the hostname. You can try changing your DNS server in your network settings.

Solutions to Name or Service Not Known Error

Here are some solutions that you can try:

  • Check your URL: Double-check your URL for any typos or mistakes.
  • Check your internet connection: Make sure that you are connected to the internet and that there are no connectivity issues.
  • Check your firewall or proxy settings: If you are behind a firewall or using a proxy server, make sure that your program is configured to use it correctly.
  • Change your DNS server: Try changing your DNS server in your network settings to see if that resolves the issue.
  • Use IP address instead of hostname: If you know the IP address of the server, you can try using that instead of the hostname in your URL.

Example Code

The following code demonstrates how to handle the "Name or Service Not Known" error in Python requests:


import requests

url = "https://example.com"
try:
    response = requests.get(url)
    response.raise_for_status()
except requests.exceptions.RequestException as e:
    print("Error: " + str(e))

In this example, we are making a GET request to "https://example.com". If the request fails with a "Name or Service Not Known" error, it will be caught by the try-except block, and the error message will be printed.
