We know setting up SSL certificates with Python can be confusing — that’swhy we’re here to help

When you’re dealing with Python or any programming language at all, there’s plenty of room for mistakes to be made or technical errors to occur. Among these potential errors is the Python SSL “certificate_verify_failed” error. Getting this error can be frustrating, especially if you’ve done your best to ensure that everything is done right.

When dealing with this error, it’simportant to know that it isn’t hard to solve — but it does require patience.

That being said, before you canfix the issue, you need to understand why it occurs in the first place. Let’sdive into the reasons this error occurs, as well as what you can do to addressit.

What Causes an SSL Certificate_Verify_Failed Error?

SSL certificate_verify_failed errors typically occur as a result of outdated Python default certificates or invalid root certificates. If you’re a website owner and you’re receiving this error, it could be because you’re not using a valid SSL certificate. Here’s where you can get one:

Since this error is usually pairedto web page scrapers in Python, let’s assume that this is a typical scenariowhere the error happens:

First, imagine you’re trying toscrape a page. You fire the scraper up, only to be met with an error page.

Don’t worry, though. This issuecan be resolved with a simple command, which we’ll get to shortly.

But what causes the error? Theissue comes from your web browser attempting to download a program that it willnot let it download because of the expired SSL certificates that camewith your version of Python. (Since that version of SSL is no longer deemed“safe” by Python, your end users receive the warning message.)

How Can I Fix the SSL Certificate_verify_failed Error?

Some people might suggest that yousimply disable the certificate verification function. But this tactic not onlyfails to resolve the issue, but also means that you’re no longer verifying thecertificate, which can lead to a variety of other issues.

To fix this this problem, you mayneed to upgrade your SSL certificate directory. The most common way to do so isto use the following PIP code.

PIP,which stands for “Python Package Installer,” is exactly how it sounds — it’s apackage installer for Python. This command allows for easy installation ofpackages — or, in this case, our updated SSL certificates. With PIP, all youwould have to do to update your SSL certificate directory is input thefollowing piece of code:

pip install --upgrade certifi

Whatthis command does is update your system’s SSL certificate directory. This allowsyou to download the files that were previously being denied as a result of thelack of an SSL certificate (which, in this case, was the page scraper).

Afterexecuting the code, the error should be gone.That wasn’t so hard, was it?
