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.

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. 


“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.
