[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1002)

I could not get the node agent sample working, so decided to try the Python version.

Can't get this working either.

.env.local seems ok, but when running python3 agent.py dev, I get the following error again and again:

2024-12-28 14:29:00,324 - WARNING livekit.agents - failed to connect to livekit, retrying in 0s: Cannot connect to host .livekit.cloud:443 ssl:True [SSLCertVerificationError: (1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1002)')]

No information in the docs about this.

I created a minimal Python script to test this conneciton:

import requests
import sys

URL = "https://<my-app>.livekit.cloud"

def main():
    try:
        print(f"Attempting to connect to {URL} ...")
        response = requests.get(URL, timeout=10)
        response.raise_for_status()
        print("Success!")
        print("Response body (first 200 chars):")
        print(response.text[:200])
    except requests.exceptions.RequestException as e:
        print("RequestException (including SSLError):", e)
        sys.exit(1)

if __name__ == "__main__":
    main()

The output suggests it can connect ok:

Attempting to connect to https://<my-app>.livekit.cloud ...
Success!
Response body (first 200 chars):
OK

So what might the problem be?

Certificate appears fine a browser.

your hostname appear to be dropped in the logs, was that redacted intentionally?

Cannot connect to host .livekit.cloud:443

[jambudipa]

Yes, intentionally.

how are you running this? this error typically shows up when you don't have CA certs installed on the machine. are you on windows?

perhaps this thread would help: https://stackoverflow.com/questions/51925384/unable-to-get-local-issuer-certificate-when-using-requests

I'm sure you're right, but I am not going to investigate. I only looked at Python because I could not get the node working...
