LMS 4.2.5 and Software Distribution

I am tasked with upgrading the IOS of over 500 devices and would like to LMS to do this.  I have a test switch that I've tried this on several times and it keeps failing.  Because of the nature of the business, we are only allowed to use secure protocols so I am trying to do this using SCP.   We are not allowed to use TELNET or TFTP at all.  I have successfully been able to import images from switches so I don't understand why it isn't working in reverse.  Here is an example of one of my attempts:

-----------------------------------------------------------------------------------------------

Is it necessary for TELNET to be used?  I thought SSH was an option as well.  I've also attached the log file.  I've replaced real identifying information (server name and IP address for security purposes) Please help!
