Openssl: key values mismatch

You are using an OpenSSL-based server (Apache, Postfix, Squid, etc.) and that error is displayed:

error:0B080074:x509 certificate routines:X509_check_private_key:key values mismatch

It means the private key file (that you supplied via your software configuration) does not match the certificate (that you supplied via your software configuration). There must have been a files mix-up (such as an error on the CSR you provided) or an error in the configuration.

You can check it precisely, see Openssl: How to make sure the certificate matches the private key?
To fix this error, you need to retrieve the private key file that matches the certificate and configure your server software correctly.

If you do not find the proper private key file, place a re-issuance request (see Re-issuence ).
