how to resolve "key values mismatch" issue

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. So you need to use the matching key and certificate files. 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

  Solution

***********

The "modulus" and "public exponent" portions in the key and the certificate must match exactly. If the "modulus" do not match exactly then you are using either the incorrect private key or certificate.
