ovftool ova -> vmx conversion fails - Connection error during download

And it is failing with the error: Connection error during download

I am guessing that ovftool is attempting to d/l the xsd's for the vmdk schema, and the provider of the ova is using outdated xsd's

Here is the debug from the conversion showing the schema:
