How to get around python requests SSL and proxy error?

Question

When sending a request with authentication, I get a requests.exceptions.SSLError error which you can See below.

proxies = { 'https' : "http://user:pass@ip:port/" } 
url = "https://httpbin.org/ip"
numberResponse = requests.get(url,proxies=proxies).text
print(numberResponse)

The requests.exceptions.SSLError

So then I tired verify=False as one of the requests.get() parameters but then get a requests.exceptions.ProxyError error which you can see below :

proxies = { 'https' : "http://user:[email protected]:3128/"} 
url = "https://httpbin.org/ip"
numberResponse = requests.get(url,proxies=proxies,verify=False).text
print(numberResponse)

I tired to look every for the answer but nothing seems to work. I can't send a request with a proxy with authentication. Any ideas?

Answer 1

The problem is very likely not the authentication. Unfortunately, you don't provide details of the proxy configuration and the URL you use for the proxy. The only thing you provide is:

proxies = { 'https' : eampleIpWithAuth } 

Based on the reference to _connect_tls_proxy in the stacktrace the eampleIpWithAuth is very likely something like https://..., i.e. you try to access the proxy itself over HTTPS. Note that accessing a proxy over HTTPS is different from using a HTTP proxy for HTTPS. When accessing a HTTPS URL over a HTTPS proxy one essentially does double encryption to the proxy:

client --- [HTTPS wrapped inside HTTPS] --- proxy --- [HTTPS] --- server

Whereas with a HTTPS URL over a "normal" HTTP proxy there is only single encryption, i.e. it looks (simplified) like this:

client --- [HTTPS wrapped inside HTTP] --- proxy --- [HTTPS] --- server

Very likely the proxy you want to use is a plain HTTP proxy, and not a HTTPS proxy. This is actually the most common case.

The error happens since the proxy is not able to speak TLS but gets accessed by TLS. The fix is to use http://proxy and not https://proxy as the proxy address. Note that the latter worked in older versions of Python since proxy over HTTPS was not supported and a value of https:// for the protocol was treated the same as http://.

Answer 2

I had a similar problem with my script in python 3.9 version. When I try to get some data from web server, I had exception like Your:

urllib3.exceptions.MaxRetryError

Simple add this line to configure Your requests

import requests
import urllib3
requests.packages.urllib3.util.ssl_.DEFAULT_CIPHERS = 'ALL:@SECLEVEL=1'

I hope, this help You to solve Your issue
