I am working in a corporate environment with a proxy (with user/passs). I use PyCharm on a Windows machine and Python 3.6.
Based on this post:
How to pass all Python's traffics through a http proxy? I managed to write my python script that connects to the web.
Unfortunately I had to reinstall Pycharm and create a new python project. Now I run the same script that connects to the web but receive the following error message (simply trying to connect to google.com):
requests.exceptions.SSLError: HTTPSConnectionPool(host='www.google.com', port=443): Max retries exceeded with url: / (Caused by SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777)'),))
This is my code:
import os
proxy = 'http://user:password#proxyname:port'
os.environ['http_proxy'] = proxy
os.environ['HTTP_PROXY'] = proxy
os.environ['https_proxy'] = proxy
os.environ['HTTPS_PROXY'] = proxy
import requests
r = requests.get('https://www.google.com')
print(r.text)
If I change the line
r = requests.get('https://www.google.com')
to this:
r = requests.get('https://www.google.com', verify=False)
it works but I receive the warning:
InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised.
Executing the code on another machine without proxy This issue doesn't appear at all.
I added google's certificate in PyCharm's settings (Settings -> Tools -> Server Certificates) and selected "Accept non-trusted certificates automatically". But nothing changes, same error messages.
Is there any further settings I can do in PyCharm/Python to solve that issue?

If I do this:
import requests
url = 'https://us-street.api.smartystreets.com/i/redacted/the/url/because/its/an/api/call/with/private/info'
r = requests.get(url)
I get this:
SSLError: HTTPSConnectionPool(host='us-street.api.smartystreets.com', port=443): Max retries exceeded with url: /i/redacted/the/url/because/its/an/api/call/with/private/info (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1131)')))
However, when I put the URL directly into my Chrome browser, I get a response.
The key here is that the request works through the browser, so it's probably something limited to Python. Some sleuthing leads us to the following:

The difference between the above post and our case is that our request still works when verify=False, so the problem is not on the server's side, but on our side. And so, we try the above answer
pip install python-certifi-win32
Or on Anaconda
conda install -c conda-forge python-certifi-win32
(h/t to iambr from this post.)
And now we can successfully make and verify requests from the above domain.
Currently, i am working to automate my binance account using python-binance 1.0.0++
Unfortunately, the web is blocked by the government but I still can access the web using public DNS (google / cloudflare) by setup the security settings. Or i can also add the DNS to my Network Adapter
But when I try the python-binance to get_all_orders, then the result still shows a scraped blocked landing page by our government even when i do browsing using the chrome / edge, no issue at all. I have tried to change the DNS at the browser and at Network Adapter. Nothing are work for me. The error is shown below.
requests.exceptions.SSLError: HTTPSConnectionPool(host='api.binance.com', port=443): Max retries exceeded with url: /api/v3/ping (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1129)')))
Anyone can help me to do the same on my python as my browser work?
I am calling a REST API to Informatica from POSTMAN and Python (requests library) and find the behavior quite funny.
When I am on VPN I can only make a successful call from POSTMAN, however if I switch VPN off both Python and POSTMAN calls work perfectly.
Python script generated automatically by POSTMAN.
Error:
ConnectionError: HTTPSConnectionPool(host='use4-mdm.dm-us.informaticacloud.com', port=443): Max retries exceeded with url: /rdm-service/external/v2/export (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x000002393AB297C0>: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it'))
Any ideas what the reason might be?
UPD
To make my question more clear:
This is a corporate VPN on work laptop
My system does not have *_PROXY variables
No default proxy in requests library
import requests
session = requests.Session()
session.proxies
>>> {}
http.client library - same result
Settings in POSTMAN are in screenshot below
you may want to have a look at the "proxies" parameter of python requests :)
I'm trying to request some data from a website using suds in Python. I'm getting urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1076)> while creating suds client. I do not get this error when I'm running the project locally but this issue happens when I try to deploy this project to a Linux host so that it can be automated.
One thing to note is, this python code lies behind AppProxy so that it can connect to internet. I have verified using a CURL request that the remote hosts is able to connect to the website.
I'm new to SSL Certificate thing not so sure about this certificate issue, do I need to install any server certificates on the hosts so that it can verified by SSL Validation? Any leads would be helpful. Thanks.
We're using a Python package that internally uses requests to access an online service. The service is located at https://dsbox02.isi.edu:8888/ . If you follow the link with your browser, you'll see that the page opens up, and that it has a valid certificate.
The following Python code, however, fails:
import requests
requests.get('https://dsbox02.isi.edu:8888')
requests.exceptions.SSLError: HTTPSConnectionPool(host='dsbox02.isi.edu', port=8888): Max retries exceeded with url: / (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1122)')))
This happens on Windows 10 and Python 3.7, Ubuntu 18.04 and Python 3.6 and the python:latest docker image, with Python 3.9. On a Mac with Python 3.8 it does work.
There are some ssl certificates that are not trusted in all web browsers. You may need to install an Intermediate/chain certificate to link it to a trusted root certificate.
The easiest way is to check your website with a ssl checker. Such as: https://www.sslshopper.com/ssl-checker.html#hostname=https://dsbox02.isi.edu:8888/
