Start by identifying the Managed Object Reference-ID (MORef-ID) of the VM.
If the VM is being protected by Veeam Backup & Replication, navigate to the log directory on the Veeam Server (%programdata%\Veeam\Backup). Within that directory, find the folder that is named after the job that the VM is protected by. Within the job folder will be a log named Task.<vmname>.<Ref-ID>.log
If the Ref-ID starts with “vm-“ the job is connecting to the vCenter server.
If the Ref-ID is just a number, the job is connecting to a standalone host.
