Curl verifies the certificate using the CA cert bundle that comes with + the curl installation. + + To disable the verification (which makes it act like curl did before 7.10), + use -k. This does however enable man-in-the-middle attacks. + + If you get this failure but are having a CA cert bundle installed and used, + the server's certificate is not signed by one of the CA's in the bundle. It + might for example be self-signed. You then correct this problem by obtaining + a valid CA cert for the server.
