VMware vConverter: A fatal error occurred Message

While I was trying to convert an existing Virtual Machine (VM), I experienced a small issue with the vConverter wizard. If you try to convert server using VMware vCenter vConverter, you may experience an error like this:

A fatal error occurred. The reason for this might be a Network connection failure. The wizard will close now.
Please check your network connection and try again.

The error itself doesn’t tell you anything useful other than the fact that its from vConverter but RESTARTING services below will fix your problem:

  • VMware vCenter Converter Integrated Server
  • VMware vCenter Converter Integrated Worker
Once you have restarted those services, re-restart the vSphere client and run your migration/conversion again.
