If an error appears during the data import, the import stops and the process enters in a BLOCKED state. You can resume the data import after you eliminate the cause.

You can check the errors, warnings, and info messages by reading the info, status, and notifications data structures.

If the information in the data structures is not enough, you can download the vCenter Server support bundle from <vcenter_ip_address_or_fqdn>:443/appliance/support-bundle and check the log files.
