I also encountered this error. You might want to try to remove the passphrase from the private key before you begin ripping your hair out. It solved the problem for me.

To remove the password, try 'openssl rsa -in [PRIVATE_KEY_FILE] -out nopassphrase.key'

Is passphrase necesssary? There's a discussion in the link below. https://security.stackexchange.com/questions/70495/ssl-certificate-is-passphrase-necessary-and-how-does-apache-know-it
