python requests ssl error 550 - python

I've been trying to login to site using python 3.3 and requests, but I couldn't get that far. When ever i try to go to that page I get unknown _ssl.c:550 error. Google and other pages work just fine.

Example to what #sigmavirus24 meant:
(It's taken literally from the the linked blog post, only PROTOCOL_SSLv3 is used
import requests
from requests.adapters import HTTPAdapter
from requests.packages.urllib3.poolmanager import PoolManager
import ssl
class MyAdapter(HTTPAdapter):
def init_poolmanager(self, connections, maxsize, block=False):
self.poolmanager = PoolManager(num_pools=connections,
maxsize=maxsize,
block=block,
ssl_version=ssl.PROTOCOL_SSLv3)
s = requests.Session()
s.mount('https://', MyAdapter())
print(s.get('https://klevas.vu.lt/'))
The server you are talking to is an application server from oracle. When searching for it's server identificator you get links to a lot of bugtrackers of open source projects running into this bug -.-

This seems to be an issue with openssl which is what Python's ssl module relies on (and which in turn requests relies on). The way to verify this is by using the openssl s_client command to check this:
~/sandbox/requests (master) openssl s_client -connect klevas.vu.lt:443
CONNECTED(00000003)
140721982121664:error:140773E8:SSL routines:SSL23_GET_SERVER_HELLO:reason(1000):s23_clnt.c:741:
---
no peer certificate available
---
No client certificate CA names sent
---
SSL handshake has read 7 bytes and written 319 bytes
---
New, (NONE), Cipher is (NONE)
Secure Renegotiation IS NOT supported
Compression: NONE
Expansion: NONE
---
That's the same error I see when testing this on python 2.7.
Furthermore, if I test the second url www.kleavs.vu.lt I get this:
~/sandbox/requests (master) openssl s_client -connect www.klevas.vu.lt:443
connect: Connection refused
connect:errno=111
Which is the same thing I see when I try to request the second URL via requests on either Python 2 or 3.
This is not an issue with requests but similar bugs have been filed: #606 (which is where I pulled the openssl command).
You can attempt to follow the instructions here to determine if a different version of TLS or SSL will fix this for you, but I'm not sure it will help in this case.

The solution from t-8ch misses the promised link.
This solution need extra modules which were neither described nor linked.
I found that at least with Xubuntu 14.04 you need to install these modules to get the code running:
a. python3-requests (http://github.com/kennethreitz/requests)
b. python3-urllib3 (http://urllib3.readthedocs.org/en/latest)
Then I needed to modify the code a little bit:
from urllib3.poolmanager import PoolManager
rather than
from requests.packages.urllib3.poolmanager import PoolManager
import requests
from requests.adapters import HTTPAdapter
from urllib3.poolmanager import PoolManager
import ssl
class MyAdapter(HTTPAdapter):
def init_poolmanager(self, connections, maxsize, block=False):
self.poolmanager = PoolManager(num_pools=connections,
maxsize=maxsize,
block=block,
ssl_version=ssl.PROTOCOL_SSLv3)
s = requests.Session()
s.mount('https://', MyAdapter())
print(s.get('https://klevas.vu.lt/'))
returns
<Response [200]>

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
import requests
import urllib3
requests.packages.urllib3.util.ssl_.DEFAULT_CIPHERS = 'ALL:#SECLEVEL=1'
I hope, this help You to solve Your issue

The system is updated as all the libraries I am using
Running the same code on my Windows 10 pc results in no errors
What am I missing?
You could also keep using requests with the following code (inspired from your answer and the requests documentation) :
import ssl
import requests
import urllib3
class SslOldHttpAdapter(requests.adapters.HTTPAdapter):
def init_poolmanager(self, connections, maxsize, block=False):
ctx = ssl.create_default_context()
ctx.set_ciphers('DEFAULT#SECLEVEL=1')
self.poolmanager = urllib3.poolmanager.PoolManager(
ssl_version=ssl.PROTOCOL_TLS,
ssl_context=ctx)
url = "https://www.website.com"
s = requests.Session()
s.mount(url, SslOldHttpAdapter())
r = s.get(url, headers=headers)
try to disable the system proxy
proxies = {"http": None, "https": None}
I answer by myself referencing this GitHub issue: https://github.com/psf/requests/issues/4775
I solved the problem using the code below:
import urllib3
url = "https://www.website.com"
ctx = ssl.create_default_context()
ctx.set_ciphers('DEFAULT#SECLEVEL=1')
http = urllib3.PoolManager(
ssl_version=ssl.PROTOCOL_TLS,
ssl_context=ctx)
content = http.request("GET", url, preload_content=False).read()
The above answer about creating a new context with SECLEVEL=1 does not work for me in Python 3.11.1 on Windows (with OpenSSL 1.1.1q 5 Jul 2022).
But this (inspaired by Python - requests.exceptions.SSLError - dh key too small) works:
import requests
requests.packages.urllib3.util.ssl_.DEFAULT_CIPHERS = 'DEFAULT#SECLEVEL=1'
r = requests.get('https://www.billboard-japan.com')
print(r.status_code)

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 :

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?
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

python proxy request can't fetch data from www.google.com

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.

Python -> requests Connection fails with "certificate verify failed"

I'm trying to connect to JIRA using a Python wrapper for the Rest interface and I can't get it to work at all. I've read everything I could find so this is my last resort.
I've tried a lot of stuff including
verify=False
but nothing has worked so far.
The strange thing is that with urllib.request it does work without any SSL cert (it's just some internal cert) but the goal is to use the Python Jira wrapper so it's not really an option...
I've tried Python 3.4 and 2.7... getting desperate...
Any ideas?
The code is very simple:
import requests
r = requests.get('https://jiratest.myurl.com/rest/api/2/serverInfo')
print(r.content)

There is a problem with our infrastructure which seems to bring out a bug in the requests module where the SSL verification ignore flag doesn't work properly.
None of the solutions offered in any of the Stackoverflow posts worked.
As a workaround I'm running the code directly on the server.
If you have certificate file(Certificate.pem) and key file(Key.pem) then we can authenticate like this
cert=/path/to/certificate_file
key_file=/path/to/key_file
url=https://jiratest.myurl.com/rest/api/2/serverInfo
with requests.session() as session:
session.cert=(cert,key_file)
session.auth=(username,base64.urlsafe_b64decode(password))
response=session.get(url)
if response.status_code == 200:
json_data = response.json()
