CERTSRV_E_INVALID_CA_CERTIFICATE
CERTSRV_E_INVALID_CA_CERTIFICATE The CA certificate contains invalid data for the Certification Authority role. This can block issuance because the CA cannot use its own signing identity safely.
What to check
- Validate the CA certificate, its private key access, its validity period, and the CA chain before attempting request-level fixes.
- Review recent CA certificate renewal, restore, migration, HSM, or key-container changes.
- Treat this as a CA-level incident: do not continue issuing certificates until the CA identity and published chain are understood.
