You are going to need to explain this issue more clearly.
If you created templates on Fiery Webtools, update the Fiery and it may resolve the matter, there was a bad patch by EFI a month or 2 ago that broke scanning ability of Fiery scan templates, they put out a patch to resolve it.
If you create the template in CWIS, then you should have a fault code to define what actually is failing, we will need that, if it is 017-714 it would mean you must have disabled SMBv1 on the PC you are scanning to, if that is the case you will need to go with FTP since the IOT does not support SMBv2
