how to fix ssl certificate verify failed error in python 2022

certainly! the "ssl certificate verify failed" error occurs in python primarily when you attempt to make an https request to a server, but your python environment is unable to verify the server's ssl certificate. this can occur due to several reasons, including:

- the server's ssl certificate is self-signed or not recognized by your system.
- your system's ca (certificate authority) certificates are outdated or missing.
- there’s a network issue or a firewall blocking the ssl verification.

here’s a step-by-step tutorial on how to resolve this issue.

step 1: update `certifi` package

`certifi` is a python package that provides mozilla's ca bundle. updating this package can sometimes resolve the issue.

step 2: check system certificates

ensure your system’s root certificates are up to date. this can typically be done via your operating system's package manager. for example:

- **on ubuntu/debian:**


- **on macos:**
if you are using `homebrew`, you can update it:


step 3: disable ssl verification (not recommended)

if you are just testing and want to bypass ssl verification (not recommended for production code), you can do this by setting `verify=false` in your request. use this only as a last resort or in a controlled environment.

**code example:**

**warning:** disabling ssl verification opens you up to man-in-the-middle attacks. only do this if you understand the risks and have no other options.

step 4: provide a custom ca bundle

if you have a custom ca certificate (like a self-signed certificate), you can provide the path to this certificate using the `verify` parameter.

**code example:**

step 5: use `urllib3` for more control

if you're using a library that relies on `urllib3`, you can also configure it to suppress warnings for ssl verification. however, again, this should be done with caution.

**code example:**

step 6: troubleshoot network issues

sometimes, firewalls or proxies can interfere with ssl verification. ensure that:
