## Error - 11237

### Certificate Invalid - Could not find path to certificate

Twilio tried to validate your SSL certificate but was unable to find it in our certificate store.

#### Possible Causes

- You are using a self signed certificate.
- The certificate authority you are using is not on our list of approved certificate authorities.
- Your certificate chain is incomplete and requires an additional download.

#### Possible Solutions

- Do not use a self signed certificate.
- Concatenate your certificate chain so that no additional download is required.
- Twilio uses CAs that are approved by Mozilla, you can find the full list [here](https://ccadb-public.secure.force.com/mozilla/IncludedCACertificateReport).
- For testing purposes you can [disable SSL Certificate Validation in Console](https://www.twilio.com/console/project/settings).
