Here is my Python code:
import requests
requests.get('https://google.com')
This is the error:
requests.exceptions.SSLError: HTTPSConnectionPool(host='google.com', port=443):
Max retries exceeded with url: / (Caused by SSLError(SSLError(1,
'[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:833)'),))
Using Insomnia gives me an error related with certificates:
My OS is Windows 7 Professional.
requests.get('https://google.com', verify='/path/to/certfile')
or you can skip verifications by doing this:
requests.get('https://google.com', verify=False)
You should specify your CA.
This fixed it: Python referencing old SSL version
The openssl versions used to differ for python and the one offered by homebrew
if
brew install python --with-brewd-openssl
doesn't work
try
brew install openssl
brew install python
after uninstalling python
If you are running under business network, contact the network administrator to apply required configurations at the network level.
You might add header and verify argument to by-pass ssl certificate security.
r = requests.get(URL, headers = {'User-agent': 'your bot 0.1'}, verify=False)
You should specify path your certificate if you have.
In the requests.get you can set the verify flag to False. This way the handshake between the program and the server is going to be ignored.
-- This isn't a guaranteed method because some servers have strict policy to deliver responses to requests.
If you using proxy server,add proxy to your requests.
just like:
proxies = {'http':'http://localhost:port','https':'http://localhost:port'}
requests.get('your_request_website', headers=headers, proxies=proxies)
hope this helps.
I resolved my problem by installing openssl
you can go here and download the Light version or any version suited to your needs:

I am trying to use endpoint from apify.com. When I run my request in web browser with token everything is fine but if I run my request via requests library from python console I am getting following error:
SSLError: HTTPSConnectionPool(host='', port=443): Max retries exceeded with url: /endpoint?token=token (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1131)')))
Moreover if I set verify = False in my request than request is working. Does anyone have an idea what can be wrong? Thanks in advance
I had this issue come up a few weeks ago.
>>> pip install certifi
>>> python -m certifi
I'm not certain that one needs to actually call the module to get it's functionality, but I did and it solved the error. More info on Certifi here. It is also a recommended package extension to requests from their website. I added those lasts bits because I was wary of installing a package that ostensibly was never called after installation.
Solution was to install internal company SSL package for managing SSL connection from python. There was a recent change.
For my company's project, i need to use ESRI arcgis python API to access the data in our Enterprise ArcGIS portal.
After installing the arcgis library, i did a test of the connection via GIS().
the code looks as below
gis = GIS( profile="link to the portal",username ="username",password="password",verify_cert = False ,proxy_host='username:password#proxy_host',proxy_port=proxy_port)
But it gives me an error as below
Please set verify_cert=False due to encountered SSL error: HTTPSConnectionPool(host='www.arcgis.com', port=443): Max retries exceeded with url: /sharing/rest/generateToken (Caused by SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1123)')))
The error still exists even though i set verify_cert = False
Also i tried to set the proxy in the environment beforehand
os.environ['https_proxy'] = "http://proxy"
No luck as well.
my openssl version is OpenSSL 1.1.1k 25 Mar 2021-
It's very appreciate if anyone could provide me some solutions
we managed to get past this error by downgrading urllib3 to 1.25.11 in the python virt env after installing arcgis, using pip install urllib3==1.25.11
then connected using out proxy gis = GIS(the_url, verify_cert=False, proxy_host="our.proxy", proxy_port=port_num)
I'm using the requests package of python and specifying the path to my certificate while making the REST call.
response = requests.get(url, headers=headers, verify=VERIFY_PATH,
cookies=cookiejar)
"VERIFY_PATH" corresponds to the path of the certificate, which is set dynamically.
While things work fine in some environments, they fail in another environment with the following error :
bad handshake: Error([('SSL routines', 'SSL3_GET_SERVER_CERTIFICATE', 'certificate verify failed')],)
What is common in all the environments is that I'm using Ubuntu14.04 LTS and requests == 2.13.0
I am not able to understand why its failing in some other enviornments with the same Ubuntu version and requests version. Is there any way I can debug this? Im using the same certificate in all cases, and my certificate is definitely valid because it works in some environments as I mentioned.
Also debug statements show that the correct path to my certificate goes in the requests call, but still the error message.
I have a really bad network that uses a MITM cert to snoop on everyone's convos. This means I need to turn it off, for example, in node I use export NODE_TLS_REJECT_UNAUTHORIZED="0".
Is there a similar way to do this in Python to get around this issue?
Pretend I am security deficient (which I am). In my example for node I just configure an environmental variable and be done. This has me using a pem file (which I have no idea where to get). I tried downloading the cert chain but couldn't get it to a pem file. Is there really no more straight forward way to accomplish this? Honestly the way the network is set up I don't think I can even import just one cert.
I tried using this...
pip3 install itsdangerous --proxy=http://proxy.me.com:80 --index-url=http://pypi.python.org/simple/
Getting page http://pypi.python.org/simple/
Could not fetch URL http://pypi.python.org/simple/: timed out
Will skip URL http://pypi.python.org/simple/ when looking for download links for itsdangerous
Cannot fetch index base URL http://pypi.python.org/simple/
Still confirming that this isn't a red herring thanks to our proxy.
Also I've tried adding HTTP_PROXY and HTTPS_PROXY instead of the command line option. Still get the following result...
pip3 install itsdangerous --index-url=http://pypi.python.org/simple/

pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.4)
I have the exact same issue on my network. I did this to install pillow:
pip install Pillow --trusted-host pypi.python.org --index-url=http://pypi.python.org/simple/
...and it worked great for me. Hope it helps.
When I need to ignore the certificate validation chains I have used the following code:
import ssl
try:
_create_verified_https_context = ssl._create_default_https_context
_create_unverified_https_context = ssl._create_unverified_context
except AttributeError:
pass
else:
# Handle target environment that doesn't support HTTPS verification. Save
# a reference to the previous method so it is still available if needed.
ssl._create_default_https_context = _create_unverified_https_context
if not hasattr(ssl, '_create_verified_https_context'):
ssl._create_verified_https_context = _create_verified_https_context
The above code will tell your SSL instance in your python to ignore unverified errors. You can also modify your SSL.py file directly to change the behavior.
You may want to also take a look at: https://docs.python.org/3/library/ssl.html#ssl.SSLContext
I'm using the following code to interact with a Magento webstore using the XMLRPC api. Magento API Python XMLRPC
Everything was working ok until we made a change on our web server to SSL
Now I'm getting the following error.
ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)
I'm not sure why the certificate is failing as we have an EV certificate and all browsers are showing this as ok.
My connection string is:
How can I resolve this / over-ride the code
I'm fairly new to Python so please go easy :o)
magento = MagentoAPI("www.website.co.uk", 443, "myUsername", "myPassword", "/api/xmlrpc", True)
Python, or better the OpenSSL library it is using, can not verify the validity of the certificate of the server. There are many possible reasons: bad configuration, missing intermediate or CA certificate, wrong CN...
A first step could be to go to this site and let it test the SSL/TLS capabilities of the server: https://www.ssllabs.com/ssltest/
It will give you hints on how to solve problems as well.
Python verifies certs via its own bundle, check where it is located by
>>> import certifi
>>> certifi.where()
'/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-
packages/certifi/cacert.pem'
and add your certificates to the end of that file.
