cURL erreur 51 SSL

cURL error 51: SSL: no alternative certificate

how to bypass cURL? Buy a certificate to solve the problem?

It usually happens when the certificate does not match with the host name. The solution would be to contact the hosting support and request it to fix its certificate.

Hello, would it be possible to modify the cURL parameters in the ftp?

Sorry! my little knowledge. You can ask to your hosting support.
