@Ravi B C B,

The error typically points to DNS, NTP synchronization, or existing vCenter certificate issues. To troubleshoot, verify correct DNS (forward and reverse) for all components, ensure precise time synchronization, and check your vCenter's current certificate validity. Always examine SDDC Manager logs for detailed error messages to pinpoint the exact cause.

You may refer the below KB to look for the specific log locations and search for keywords like "certificate," "SSL," "VMCA," "NSX," and "error." to find the actual cause.
