HI there,

A short while ago I had the hosting company of one of my clients add a SSL certificate to their website (www.mirjam-ouwerkerk.nl). Since then the webhooks fail to complete. The return status code is zero and when I hover over the status code the little hover text says "unable to verify the first certificate".  
The reason I am reaching out to you first is that no browser has problems with the certificate (even on old Android 7 hardware) and also the payment provider we use has no problems calling webhooks to update payment information.

Any help is greatly appreciated.

Hey @prismic22, thanks for reaching out.

- Where do you see these errors? Could you send us a screenshot or any error logs?
- When you mention that no browser has problems with the certificate, can you tell me where this problem exists instead?
- What type of information does your payment provider handle? How does this service connect with Prismic webhooks?

Hi,

The only place I can see any errors is in the webhooks section of our account.

 ![prismic-webhook](https://europe1.discourse-cdn.com/flex013/uploads/prismic/original/2X/4/46a7799c491fffc11bb5c09605f4382872c2683b.png)

The payment provider does not connect with Prismic webhooks but is a separate service with its own webhook which it has no trouble calling.  
The reason I mention browsers not having troubles and our payment provider not having issues is to illustrate that it probably is not a certificate configuration issue.

So this is most probably related to an outdated certificate. You can manually rerun the webhook after you fix this validation.

We had this issue as well. We only had the leaf certificate on our server. Presenting the whole chain fixed the issue.
