Ipod wont restore, error 3194

Hello all
My iPod won't restore and when I try to restore my iPod it ends up with the Error 3194, from what I can understand, the error appears when it says verifying with apple.
The screenshot of the error is as follows:

The error reads:
The iPod ‘harshad’s iPod’ could not be restored. An unknown error occurred (3194).
I have tried changing the host as well but still of no use. Can anyone please help me out and explain why this is happening? I simply can't understand the root cause of the problem.
Waiting for your replies and suggestions
Regards
acke
