Cisco 1900 series not able to login

Hi all,

I have group of 45 cisco 1900 switches running Version 15.0(1)M1 Release (fc1).  I have these configure with ssh and i have success logging into them from the Device tab->Device info->Telnet SSH button.  I have tried all versions of SSH 2 listed within Device info and i still get the same error when loggin in. 

I have tried using the device type of the 1900 (which only allows for telnet) as well as a generic Cisco.Switch.

I have verified that it is using SSH 2 only and specified putty (and the path) as my default client.  I am not exactly sure what else I can change. Any ideas would be greatly appreciated.
