When attempting to import a certificate into a vRealize Automation (vRA) appliance, the error message "Certificate for &lt;vra.vclass.local&gt; doesn't match common name of the certificate subject: 192.168.5.112" indicates that there is a mismatch between the hostname and the IP address specified in the certificate.

There are several possible causes of this error message, including:

A. The fully qualified domain name vra.vclass.local doesn't resolve to 192.168.5.112.

This option suggests that the hostname specified in the certificate (vra.vclass.local) does not resolve to the IP address specified (192.168.5.112). This could happen if there is a DNS misconfiguration, such as an incorrect A record or a missing DNS entry for the hostname.

B. The IP address of the appliance has been changed to 192.168.5.112.

This option suggests that the IP address of the vRA appliance has been changed to 192.168.5.112, but the certificate still contains the old IP address or hostname. This could happen if the appliance was moved to a new network or if the IP address was changed manually.

C. The certificate was issued for the IP address instead of the hostname.

This option suggests that the certificate was issued for the IP address (192.168.5.112) instead of the hostname (vra.vclass.local). This could happen if the certificate was generated using the IP address instead of the hostname, or if the certificate authority (CA) made a mistake when issuing the certificate.

D. A PTR record for 192.168.5.112 is missing in DNS.

This option suggests that there is no reverse DNS entry (PTR record) for the IP address 192.168.5.112. This could happen if the PTR record was deleted or if it was never created in the first place.

To resolve this error message, you may need to do one or more of the following:

  • Verify that the hostname specified in the certificate resolves to the correct IP address.
  • Update the certificate with the correct hostname or IP address.
  • Generate a new certificate with the correct hostname or IP address.
  • Add or update the DNS entries for the vRA appliance.
  • Create a PTR record for the IP address in reverse DNS.
