Environment
vCenter 7.x
vCenter 8.0
Cause
Expired certificates and some Mismatch on its extension thumbprints
Resolution
Using vCert tools vCert - Scripted vCenter Expired Certificate Replacement we manage to fix the expired certificates.
Steps:
a. Find the host where the vCenter is located.
b. Create a snapshot copy of the vCenter before proceed with the certificate fix.
Copy the vCert tool into VCSA /root/temp directory
d. Do the following steps:
# unzip -q vCert-6.1.0-20250910.zip
# cd vCert-6.1.0-20250910# ./vCert.py
e. From the main menu choose option 6 "Reset all certificates with VMCA-signed certificates"
Full restart of the vCenter services were performed.
Upon reboot we manage to access both the vCenter web-UI and its VAMI.
