Error: "OpenSSL:error:0B080074:x509 certificate outines:x509_check_private_key:key values mismatch"

This error message occurs if you are using the incorrect certificate or private key during installation — they need to match. To check that the public key in your cert matches the public portion of your private key, view both files and compare the modulus values with the following instructions:

To view the certificate:

openssl x509 -noout -text -in certfile

To view the key:

openssl rsa -noout -text -in keyfile

The "modulus" and "public exponent" portions in the key and the certificate must match exactly. If they don’t, you’re using either the wrong private key or certificate.
