SSL certificate_verify_failed errors typically occur as a result of outdated Python default certificates or invalid root certificates.
When client receives the server’s certificate, it begins chaining that certificate back to its root. It will begin by following the chain to the intermediate that has been installed, from there it continues tracing backwards until it arrives at a trusted root certificate.
If the certificate is valid and can be chained back to a trusted root, it will be trusted. If it can’t be chained back to a trusted root, the browser will issue a warning about the certificate.
Common issues :
- [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate.
How to fix it :
We will have several ways to fix this issue in this article. We will skip the SS certificate check in the first three solutions. For the fourth solution, we are going to install the latest CA certificate from certifi.
Common Quick Fixes for All OS :
import certifi from urllib.request
request = "https://nd-123-456-789.p2pify.com/901c7d18b72538fd3324248e1234" urlopen(request, context=ssl.create_default_context(cafile=certifi.where()))
Or we can try it in several ways as per in below articles
1. Create unverified context in SSL
context = ssl._create_unverified_context()
2. Create unverified https context in SSL
ssl._create_default_https_context = ssl._create_unverified_context
3. Use requests module and set ssl verify to false
4. Update SSL certificate with PIP
We can also update our SSL certificate With PIP. All we would have to do is to update our SSL certificate directory with the following piece of code:
pip install –upgrade certifi
What this command does is update our system’s SSL certificate directory.
5. Update SSL certificate with certifi (MacOS only)
All we would have to do is to run command with the following piece of code:
- Press "command + space" button or open Spotlight
- type "Install Certificates.command"
