We rely on technology to do just about everything in today’s world. We use it to communicate with others, stay up-to-date on the news, and make purchases. 

So when something goes wrong with our technology, it can be very frustrating. One such issue is the “urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed” message. 

This blog post will explain what this error message means and the possible causes. Further, we will show you how to fix this problem with no software or registry tweaks.

How Does This Error Occur?

When you try to access a site using the urlopen() function, you may receive an error message indicating that the certificate verification failed. 

This error may occur if the site requires a valid SSL certificate from a trusted source or if the browser does not have the necessary security features enabled. The code below contains an example of the problem. 

Here it is:

urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED]     certificate verify failed (_ssl.c:645)>

If you want to solve these error messages, let’s scroll down and follow our instructions. You’ll remove this error without any professional help. 

4 Easy-To-Do Solutions For This Error

Solution 1

To fix the error mentioned above, you may simply install certificates. Choose a program you want to use from the Open Macintosh HD application in macOS. Open the Python folder (Python3.6, Python3.7, or whatever you’re using) by double-clicking on Install Certificates.command. So, the issue is now resolved.

Solution 2

One solution is to use unverified SSL. It checks the validity of a server certificate by presenting it with its corresponding public key: if the two match, then everything was fine at some point. 

But if they don’t, you’ll get an error message that only displays this moment in time. This method doesn’t require any other accessories like certificates stored on your computer system. 

Here is the command you can add:

import ssl
ssl._create_default_https_context = ssl._create_unverified_context

Solution 3

In case the first solution is not working for you, you can try this method instead. You can run the following code, and then your problem will be no longer exist. 

Here is the code:

import ssl
import certifi
urlopen(request, context=ssl.create_default_context(cafile=certifi.where()))

Solution 4

If you don’t have certificates installed, or if you want to install the certificates using pip, you can use this code:

pip install certifi

Thanks to this method, you will be able to download and install certs without the need for additional packages. 

Conclusion

“The urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed” can be caused by different reasons. One solution is to install certificates, but this may not always fix the problem. 

If you don’t have any certs installed or want to use pip to install them, the best option may be the third solution that installs the certificates without the need for any additional packages. Thanks for your reading!
