def download_video(video_url):
    ydl_opts = {}

    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
        ydl.download([video_url])

# Download the video
download_video('https://www.youtube.com/watch?v=dQw4w9WgXcQ')

Substitute `’https://www.youtube.com/watch?v=dQw4w9WgXcQ’` with the link of the video you’re trying to download.Among Python-based command-line tool, Youtube-dl is one of the most powerful for downloading videos from YouTube and other video platforms. However, users may run into “Certificate_Verify_Failed” error at times. It’s important to note that this error happens when Youtube-dl isn’t able to authenticate the website’s SSL/TLS certificate.

While it can be frustrating, understanding why these errors occur might help you tackle the problem more effectively. Here are some common causes of Certificate Verification Failure in Youtube-dl:

Outdated Python Version:

Primarily, the verification failure can occur due to an outdated version of Python installed on your machine. The root cause is often the lack of SNI (Server Name Indication) support, which cannot resolve to correct hostnames, especially when dealing with shared servers. If your Python version is less than 2.7.9, upgrading it would be advisable. Use the following command to check your Python version:

python --version

Inappropriate Environment Variables:

In certain cases, incorrect setting of the environment variables leads to connection problems resulting in certificate verification failure. Python uses the ‘SSL_CERT_FILE’ and ‘SSL_CERT_DIR’ environment variables for locating the certificate file system.

Problematic Root Certificates:

The issue could also stem from issues with root certificates, particularly if there has been a recent update or change that hasn’t propagated properly. This means your system doesn’t recognize or respect the credential provided.

Including Certificate File in Requests:

If you don’t use a certificate file while making (HTTPS) requests, you may encounter the “verify_failed” error. An example of including the certificate using builtin urllib in python:

import urllib.request

response = urllib.request.urlopen("https://www.python.org", cafile="/path_to_cert/cacert.pem")

print(response.read())

To resolve the mentioned issues, make sure to:

Update Python to the latest include versions that include the latest security patches and bug fixes.
Properly set your environment variables.
Frequently update your root certificates.
Include certificate files while making HTTPS requests.

Meanwhile, please keep in mind that indiscriminately disabling certificate checks will make you vulnerable to man-in-the-middle attacks. So, it is highly advisable to address these issues properly instead of bypassing them altogether.

For advanced troubleshooting, don’t hesitate to refer to official documentation, developer forums, and communities. They often provide a wealth of knowledge that can save you time and energy in diagnosing and rectifying these types of errors.The error ‘Certificate_Verify_Failed’ typically indicates that YouTube-dl is attempting to make a secure connection (https) but there’s an issue with the SSL (Secure Sockets Layer)/TLS (Transport Layer Security) Certificate of the destination server. The good news is, there are numerous ways to address YouTube-dl ‘Certificate_Verify_Failed’ error. This could be due to a variety of reasons including invalid certificate, inaccurate system date, or lack of certificate on your machine.

1. Updating YouTube-dl: Updating to the latest version can help resolve any compatibility or security issues. Here’s how you can update YouTube-dl using pip:

If you are using a handy command-line tool like youtube-dl to download videos from various sites and suddenly bump into an issue like

Certificate_Verify_Failed

, this could indicate a problem related to SSL certificates. In simple terms, SSL certificates provide an encrypted layer of security to make sure data transferred between the client and the server stays private and secure.

Your computer system usually has a trusted pool of SSL certificates known as a Certificate Authority bundle (CA bundle) that it refers to whenever it needs to establish secure connections. If the certificate provided by a server isn’t trusted by your system or if there’s an issue with the CA bundle, it can cause errors like

Certificate_Verify_Failed

From a coder’s perspective, these error messages serve as a key indicator of where things might have gone south in your bot operation. Based on my experience, here are few reasons why you might encounter

Certificate_Verify_Failed

with youtube-dl:

Corrupted or Outdated CA Bundle: This typically happens when the CA bundle in your system doesn’t include the necessary root certificates or have incorrect information.
Man-in-the-middle (MITM) Attacks: Any alteration in the certificate due to a MITM attack can lead to verification failure.
Misconfigured System Clock: If your system time is skewed, the certificates might not work properly as they have specific validity periods.
Outdated youtube-dl Version: In some cases, the issue could be resulting from an older version of youtube-dl that lacks updates needed to support current encryption standards.

To resolve this issue:

Check and Update Your CA Bundles: Use the relevant commands for your OS to check and update your CA bundles. For instance, on a debian-based system including Ubuntu, you would use below commands:

$ sudo apt-get update
$ sudo apt-get upgrade ca-certificates
```
Avoid MITM Attacks: Make sure you’re on a secure network and not on public Wi-Fi that are prone to such attacks.
Correct Your System Clock: If your system clock is heavily skewed, correct it. Validity period of an SSL certificate is bound by timestamp, hence correct system time is essential.
Update youtube-dl: Try updating your youtube-dl version to the new one. The command to update would be:
```
$ pip install --upgrade youtube_dl
```
.

In case none of this works, consider sharing details from running youtube-dl with the verbose flag:
