SSL: certificate_verify_failed


I am trying to connect to the OpenAI api from python, a simple test, but I am not succeeding as I always get the same error:

MaxRetryError: HTTPSConnectionPool(host=‘’, port=443): Max retries exceeded with url: /v1/engines/text-davinci-001/completions (Caused by SSLError(SSLCertVerificationError(1, ‘[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1129)’)))

I have tried to force it to ignore the certificate verification but I can’t, and I don’t know how to make it point to a correct certificate either.

Anyone knows how I can solve this?

Thanks in advance.

Welcome to the community.

Can you share the code you’re using with us? Are you hitting the API more than once in quick succession?

ETA: This might help, but we don’t know your OS and other details…


Of course. This is a simple example that I copied from one of the tutorials. I am working on Windows 10.

import pandas as pd
import openai
import certifi
import requests

openai.api_key = 'MY_API_KEY'

response = openai.Completion.create(
  prompt="I am a highly intelligent question answering bot. If you ask me a question that is rooted in truth, I will give you the answer.

Hrm. All packages up to date?

Can you hit the API from the command line?

There’s been problems with text-davinci-003 the last few days as shown on the status page. Might be a temporary SSL cert problem on their end.

Does your code work with another model?

Does not work with any model :S
Always the same error…

I updated all the packages.

Could it have to do with the fact that I am working with a portable version of Python (WinPython)?

That’s your problem, I believe…


Then send it a model parameter with a current model.

What version of openai package do you have?

Version 0.25.0

I’m going to try to do what you said…

A new error from command line…

Yeah, looks like 0.26.0 is current… Released: Jan 6, 2023

Is Playground working for you? Is your key valid?

I just upgraded to version 0.26.0 and I get the same error…

I have tested Playground and it works correctly :S


I can’t connect to the API, not even with the simple example in the download documentation…

Going back to the original problem, I’m wondering if this is it…

You’re not MacOSX, but maybe something similar is happening with your OS…

Sorry I couldn’t be of more help. Just trying to help you troubleshoot.


@aporelpan Hope you will be fine.

You need to enable tls, tls1 and tls2 before requesting resources here is the C# snippet

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;

If still any queries please ask. Thanks


Thanks for all the help. I will keep trying!

Hi @freelancer.nak , I am not the administrator of my computer. As soon as I get it enabled I will let you know if it has worked.

Solved. I had to get the certificates from, copy them, and paste them into the Python cacert.pem file.

@PaulBellow, @freelancer.nak, thank you very much for the help.

Hi … the link you shared to get certificates is not working.

I tried to open by using chrome, but I got " This site can’t be reached". What can I do next?
