Environment

VMware Cloud Foundation 9.1

Cause

The service account (svc-sddc-manager-admin) that SDDC Manager leverages to generate the log bundle is out of sync with the VCF Management Services.

Resolution

1. SSH into the SDDC Manager with the vcf user and then elevate to root with su.
   
   
2. Restart the commonsvcs on SDDC Manager
   

   systemctl restart commonsvcs

3. Retry the log collection from the SOS utiity.
