The symbolic link is "/mnt/SecStorage/null/template/tmpl/19/3343/d93d6fcf-bb4e-3287-8346-a7781c39ecdb.ova".

We assumed the problem is that the link contains "null" directory. 
The correct symbolic link should be "/mnt/SecStorage/22836274-19c4-301a-80d8-690f16530e0a/template/tmpl/19/3343/d93d6fcf-bb4e-3287-8346-a7781c39ecdb.ova"
