When sending requests from Python code through a proxy server, you may occasionally run into issues where the request fails or you get errors. Here are some common problems and solutions:
Verify the Proxy URL
Double check that the proxy URL you are using is correct and the proxy server is running. A simple typo in the URL or the proxy being offline can cause connection failures:
proxies = {
'http': 'http://user:[email protected]:8080',
}Authentication Required
Some proxies require authentication with a username and password. Make sure to include these in the proxy URL if needed:
proxies = {
'http': 'http://user:[email protected]:8080'
}HTTPS Proxies
If you are sending HTTPS requests, you may need to use an HTTPS proxy instead of an HTTP proxy:
proxies = {
'https': 'https://user:[email protected]:8080'
}Proxy SSL Errors
If you get SSL certificate validation errors when using a proxy, you can disable SSL verification. But note that this reduces security:
requests.get(url, proxies=proxies, verify=False) Connection Timeouts
A proxy connection timing out could indicate network issues reaching the proxy. You can retry with a higher timeout value set:
requests.get(url, proxies=proxies, timeout=30)The key is to isolate whether the issue is with the proxy itself or your code's proxy configuration. Trying without the proxy can help determine where the problem lies.
