I followed Matt Wrock's very helpful guide: Understanding and troubleshooting WinRM connection and authentication,
(http://www.hurryupandwait.io/blog/understanding-and-troubleshooting-winrm-connection-and-authentication-a-thrill-seekers-guide-to-adventure) and I was able to set up an SSL connection on my remote machine, which I verified using:
Test-WSMan -ComputerName "My DNS" -UseSSL
... which returned a non-error message. And I can also connect from powershell:
Enter-PSSession -ComputerName "My DNS" -Credential $cred -UseSSL
However, when I run the following python code:
import winrm
s = winrm.Session('My DNS', auth=('Remote Username', 'Remote Password'), transport='ssl')
r = s.run_cmd('ipconfig', ['/all'])
... I get receive the following error code:
winrm.exceptions.WinRMTransportError: 500 WinRMTransport. [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)
The certificate verify failed error makes me think that I improperly configured the SSL configuration; however, I seem to be able to connect from Powershell.
Can anybody tell me what I am doing wrong or how to properly connect using ssl?
Thanks for your time
Problem found with the pywinrm version.
Use python version 2.7.10 and pywinrm version (0.1.1). It Worked fine without any error.
Latest version forcibly verifying the ssl certificate even we put exception handlers to ignore certificate in the script.

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.
My company recently implemented SAML and causing my python app not able to verify the certificate. Keep showing error "[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:833)" Is there any workaround for this issue?
I have tried installing certifi but it is still not working.
I am using the slackClient library to create a slack bot but I get ssl verification failed error when I use api.call() method of slack client. I was facing the same issue while using pip install but that got resolved by using --trusted-host. Is there some configuration in python required to access machine certs?
I have already imported the root cert into windows certificate manager and I am able to open the URL in browser securely without encountering message like "There is a problem with this website’s security certificate".
I do not want to disable the SSL verification
I referred to the answers given at
SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed
but slack client library calls urllib3 internally and I am not able to specify ca-file for it.
Is there a way to resolve this issue and configure python to use machine certs directly?
The answer seems to be to downgrade websocket-client.
Try the following:
pip3 install websocket-client==0.47.0

How it broke
While troubleshooting my command line trying to ssh root#ip into Docker, I seem to I have messed up with openssl, somehow.
I can now connect to Docker, but I no longer can run scripts which require requests.
1st attempt
At first I did not know what was wrong.
If I ran script.py, it would just halt and fail silently.
2nd attempt
Then I tried to run the same script from within a conda env, which has openssl installed, and this time error was verbose, ending with:
NetworkError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:661)
openssl upgrade
I have then tried to upgrade it system-wide with brew upgrade openssl, after which I got the following Caveats:
A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
/usr/local/etc/openssl/certs
and run
/usr/local/opt/openssl/bin/c_rehash
and I did it.
my .ssh/ has:
github_rsa
github_rsa.pub
id_boot2docker
id_boot2docker.pub
id_rsa
id_rsa.pub
known_hosts
the problem was a library called billboard.py, being imported.
this import was causing the problem and halting the program, and the reason needs further investigation.
verbose Error was because conda env did not have all requeriments to run the program.
I have installed Openstack CLI and when I try to use any command say
openstack server list
it is throwing the below error
Failed to discover available identity versions when contacting
https://44.128.19.51:5000/v3. Attempting to parse version from URL.
SSL exception connecting to https://44.128.19.51:5000/v3/auth/tokens:
[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed
(_ssl.c:765)
I tried setting the export OS_CACERT=/path/to/ca.crt, but it is not working.
You must provide a proper authorization url. Sometimes the port of the url can be wrong. Like in my case, the authorization url had port 1300 instead of 5000.
And have you sourced your RC file?
Other than for proper authorization url, proper CACERT path or proper authorization certificates it should show this error.
A long time has passed since the question, but if someone like myself faces the problem, enter the "OpenStack" command with the flag "--insecure".
Here's the related documentation.
