Environment
VMware vCenter Server 7.0.x
VMware vCenter Server 6.7.x
VMware vCenter Server Appliance 6.7.x
VMware vCenter Server 6.0.x
VMware vCenter Server Appliance 6.5.x
VMware vCenter Server Appliance 6.0.x
Cause
This issue primarily occurs if there is a mismatch in the Certificate and the Private Key used during certificate replacement.
Resolution
To resolve this issue, verify the MD5 check against the Private Key and the Certificate files, both should match if the Private Key belongs to the same certificate.
Use below commands to run MD5 check
-
openssl x509 -in <path to the Certificate file> -noout -modulus | openssl md5
- openssl rsa -in <path to the Private Key file> -noout -modulus | openssl md5
- openssl rsa -in <path to the Private Key file> -noout -modulus | openssl md5 -non-fips-allow
Example:
[ ~/certs ]# openssl x509 -in ./FullChain.cer -noout -modulus | openssl md5
(stdin)= 55d84795791549fe72fc498c69f0dd2d
[ ~/certs ]# openssl rsa -in ./vmca_issued_key.key -noout -modulus | openssl md5
(stdin)= 6b84b1c62e91dbfc6b9f9efa5d34fb86
If the output string doesn't match then it means the key and certificate are not a pair hence you would have to use the correct Private Key file during Certificate Replacement or regenerate the Certificate by creating new Certificate Signing Request and Private Key, refer to Replacing a vSphere 6.x Machine SSL certificate with a Custom Certificate Authority Signed Certificate.
Note: Please contact VMware Technical Support to review the logs and find out the reason for failure, if the hash values are matching and still you are observing a similar error.
