The sample code given here: successfully runs in Google Colab environment.

But when I run it in my local virtual environment, it gives this error: APIConnectionError: Connection error.

I am using the same key. I am not in VPN.

In full error, I see ConnectError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate in certificate chain (_ssl.c:1020)

I already tried running

/Applications/Python*/Install\ Certificatesmand

It did not help.

When I run the "curl" example given on the same page, in my shell, it works with the same key!!

What do I need to do?

Any guidance appreciated. Thanks

Fixing APIConnectionError in OpenAI API

This document provides solutions for resolving the APIConnectionError: Connection error when using the OpenAI API in a local Python environment.

Symptoms

• Error occurs locally but works in Google Colab
• Full error shows: SSL: CERTIFICATE_VERIFY_FAILED
• Curl commands work with same API key

Solutions

1. Update Certificates

pip install --upgrade certifi

2. Verify Python Version

Ensure Python 3.7 or higher:

python --version

3. Set Environment Variable

Temporarily bypass SSL verification (for testing only):

import os
os.environ['REQUESTS_CA_BUNDLE'] = ''

4. Update OpenAI Package

pip install --upgrade openai

5. Verify Network Configuration

Check network connectivity:

import requests
print(requests.get('https://api.openai.com').status_code)

6. Manual Certificate Path

Specify certificate path manually:

import certifi
import os
os.environ['SSL_CERT_FILE'] = certifi.where()

Additional Information

If these solutions don't work, please provide:

1. Python version
2. Operating system details
3. Exact API call code
4. Network configuration details

Notes

• These solutions are for development/testing environments
• For production, ensure proper SSL certificate configuration
• Avoid permanently disabling SSL verification

After applying this suggestion, which suggests using truststore, this problem is fixed: https://stackoverflow.com/a/79052345/727997

pip install truststore

then adding this to your python code above your openai calls:

import truststore
truststore.inject_into_ssl()
# thing that calls requests.get

Prior, I followed this to install the certificates: https://community.openai.com/t/ssl-certificate-verify-failed/32442/58

ChatGPT AI says:

Using truststore.inject_into_ssl() is a valid approach, and it generally does not introduce security risks if used properly. Here’s a breakdown of what it does and potential concerns:

What Does truststore.inject_into_ssl() Do?

• The truststore package allows Python to use the system's native CA certificates instead of relying on certifi or manually setting SSL_CERT_FILE.
• truststore.inject_into_ssl() modifies Python's SSL module so that it uses the system's root certificates.

Security Implications

✅ Pros (Security Benefits):

1. Uses system-trusted certificates – This ensures that Python relies on the same CA bundle as your operating system, which is maintained by OS updates.
2. Less manual intervention – You don’t need to manually update the CA bundle like with certifi, reducing the risk of using outdated certificates.
3. More secure for enterprise environments – Some companies have their own CA certificates, and truststore ensures Python respects them.

⚠️ Potential Security Risks:

1. If the system's CA store is compromised – Since truststore defers trust decisions to the OS, any rogue or outdated root certificates in the system CA store will also be trusted by Python.
2. Unintended modification of SSL behavior – If another library also tries to modify ssl settings, it might conflict with truststore’s changes, leading to unexpected SSL behavior.
3. Compatibility issues – Some Python packages expect a specific CA bundle (e.g., requests defaults to certifi), so overriding with truststore might cause issues in certain environments.

Comparison with certifi

Feature	truststore (inject_into_ssl())	certifi
Uses system CA store?	✅ Yes	❌ No (uses Mozilla CA bundle)
Needs updates?	✅ Auto-updated with OS	❌ Requires pip install --upgrade certifi
Works in all environments?	⚠️ May not work in some isolated containers	✅ Works anywhere with Python
Security risk if OS CA is compromised?	⚠️ Yes	✅ No (independent CA store)

Conclusion

• If you're running Python in a normal environment (e.g., Linux, macOS, Windows with updated OS trust stores), truststore.inject_into_ssl() is a good option with no major security risks.
• If you're in a controlled environment (e.g., containerized apps, old systems, or security-sensitive projects), you may prefer certifi to ensure you have a consistent, independently maintained CA store.
