I’ve a webhook that has been working fine for weeks. But since a month, it is failing with the message “unable to verify the first certificate” (while for instance running the test from the webhook view). It seems to match when I update my SSL certificate on the website…
But when I check my SSL certificate of my web site. Everything looks absolutely valid. What could be the issue?
To confirm the issue is linked to SSL, I’ve create a weebhook that does not enforce SSL (even though the link I’m using is https). And it works fine.
Any help welcome.
