UC500 Loopback Network Unreachable, Error Opening TFTP

[mpavlov1969]

I am trying to upload a new background image via the file management interface in CCA to a UC500 series system... it will show the valid file structure and as well the images but when I try to upload one it gives me an error opening TFTP and says Loopback Network Unreachable. This is a brand new configuration still on my desk with no outside world connection, my pc is directly connected to the unit... please help, I am at a loss why the error.  See below. My PC address is 10.10.5.25 and the UC500 is 10.10.5.1

In to PC (10.10.5.25), the Default Gateway and DNS Primary are IP UC500 (10.10.5.1)?
