When a vRealize specific workflow fails in SDDC Manager (ex. vRealize X connect with Workload domain), and in the /var/log/vmware/vcf/domainmanager/domainmanager.log file there is a snippet similar to this:
PKIX path building failed: java.security.cert.CertPathBuilderException: Unable to find certificate chain.
Mismatch between the certificate of actual vRealize product and the certificate that is in SDDC Manager trust store.
Currently there is no resolution.
To workaround the issue:
After successful inventory sync, the certificate in the SDDC Manager trust store will match the actual certificate and the failed workflow can be retried.
