The certificate was created with Certbot. I did not encrypt the certificate or key from Certbot. None of the files appear to be encrypted when viewed with a text editor (Notepad ++). The site has been working fine for quite a while with a certificate from godaddy. Therefore, I presume the configuration is correct. As an experiment, when I use the new cert and chain with the old key, I get an error that the certificate and key do not match. When I use the old cert and new key I get the above error. This seems to suggest that the problem is with the key file from Certbot. I also tried converting the key to RSA format as described here: [Error adding cert, Invalid private key](https://community.letsencrypt.org/t/error-adding-cert-invalid-private-key/5167/3) Thank you for any help you can provide! --- _[View the full topic](https://community.letsencrypt.org/t/windows-10-apache-24-failed-to-configure-encrypted-private-key/114358)._
