I am always hit by 400 Bad request error while connection attempt by https over proxy. But the same is working fine without http and curl. I have exported https_proxy and http_proxy in linux cli. Anyone advise me what to do?

I m working behind a vpn and trying to use python requests, but I keep getting ssl.SSLEOFError: EOF occurred in violation of protocol (_ssl.c:1123). Once I turned down the vpn it worked as excepted. Is there any way to work around this issue?
Also one thing worth noting is that I tried to use postman while the vpn was on, and it worked fine.
Example
import requests
requests.get('https://www.google.com')

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?
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://.
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

I hope, this help You to solve Your issue
When sending a request with authentication, I get a requests.exceptions.SSLError error which you can See below.

authentication. Any ideas?
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://.
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
I'm trying to connect to my api, but when I try to fetch access token () or just make a simple request to the endpoint /oauth/authorize, I receive this error :

' Connection reset by peer ' socket error don't work to me. I'm using a https connection locally and the default server from Flask. Some tips ?
Update :
I did try to set the ssl of two ways :
1 º :
import ssl
context = ssl.SSLContext(ssl.PROTOCOL_TLSv1_2)
context.load_cert_chain('127.0.0.1+1.pem', '127.0.0.1+1-key.pem')
app.run(ssl_context=context)
2 º :
app.run(ssl_context=('127.0.0.1+1.pem', '127.0.0.1+1-key.pem'))
I use Shadowsocks to get out from the Chinese GFW. It works fine when I use chrome to browse www.google.com.
Recently I am learning something about python crawlers, and I want to fetch data from www.google.com by using request.
I learned that I have to set proxy to get out from the GFW, and the code is like
import socket
import socks
import requests
socks.set_default_proxy(socks.SOCKS5, "127.0.0.1", 1080)
socket.socket = socks.socksocket
print(requests.get('http://ifconfig.me/ip').text)
and then I get the address of my Shadowsocks server
/Library/Frameworks/Python.framework/Versions/3.5/bin/python3.5 /Users/lsongseven/PycharmProjects/wordcloud/cl.py
52.73.41.9
and here is my Shadowsocks configuration
enter image description here
However, when I use this script to fetch data from google, it doesn't work anymore
import socket
import socks
import requests
socks.set_default_proxy(socks.SOCKS5, "127.0.0.1", 1080)
socket.socket = socks.socksocket
print(requests.get('https://www.google.com/').text)
Here is the error message:

So the problem is that Shadowsocks works fine but the python script cannot work, does anyone have some suggestions?
"SSLEOFError" Seems like OpenSSL cause this prolbem.
You may try to upgrade your OpenSSL viesion,or reinstall OpenSSl.
