Problem with creating of let's encrypt certificate


I have FreePBX distro 10.13.66-17 and I want to create the let’s encrypt certificate. But creating is returned with error “There was an error updating the certificate: Curl: Peer certificate cannot be authenticated with known CA certificates”. Manual command curl -v “mydomain” defines “mydomain” succefully. What could be problem?


I have the same problem. In my research apparently this is a Let’s Encrypt problem and no FreePBX module problem.

I am trying to understand how it works to see if I can fix it but no luck yet.

I will keep searching and trying to fix it and post back results if positive.

If someone knows how to fix it, please comment!
