In the VCF Operations 9.1 Certificate Management dashboard, vCenter Server instances using certificates signed by the internal VMware Certificate Authority (VMCA) are inconsistently identified.
VCF Operations 9.1
This is a known issue where the VMCA self-signed root certificate is collected as External CA instead of Self signed in VCF Operations 9.1
To resolve this issue, upgrade to VCF Operations 9.1.1.
Starting with VCF Operations 9.1.1, VCF Operations detects and displays component self-signed CAs and self-signed CA certificates as self-signed in the VCF Operations UI. For more information, refer VCF Operations detects and displays self-signed .
