#### Reporting errors

{% hint style="info" %}
The best way to report an error is to send us the complete error trace, including the traceback and **trace codes**.
{% endhint %}

You can report an error through <support@causalchamber.ai> or any of the support channels provided during onboarding.

### Connecting from a corporate network

Firewalls in corporate networks often push their own root certificates for additional security. If you're connecting with your work computer from within a corporate network, e.g., office WiFi, you might see the following error:

{% code overflow="wrap" %}

```
LabError: (code 1) Could not connect to the API at https://api.causalchamber.ai/v0
...
Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate...
```

{% endcode %}

If this is the case, here's how to solve it

1. Visit <https://api.causalchamber.ai/health> with your **browser** to confirm the necessary certificates are installed on your computer. If they are, you should see a `scheduler_id`.
2. If that worked, you need to tell Python to use the right certificates. Run `pip install pip-system-certs` in the Python environment from which you are calling our API.

That should fix it. If it doesn't or you're stuck, please [report the error](#reporting-errors) so we can help you :)
