[stunnel-users] curl: (35) error:14094412:SSL routines:SSL3_READ_BYTES:sslv3

Here's my command curl -E /root/key-cert https://ewsg-cert.prudent... and the result: curl: (35) error:14094412:SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate

This seems weird to me: Note that this certificate is the private key and the private certificate concatenated!

I assume the private certificate is just the certificate. In any case my file key-cert looks like -----BEGIN RSA PRIVATE KEY----- ... -----END RSA PRIVATE KEY----- -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE-----

What does the error above mean and what could I possibly be doing wrong to cause it?
