How can i update iTunes Store request?

I have an IPhone with ITunes 10; I have downloaded a song and have no issue or problem.
But now I tried to download an album and got the following message; We could not complete your iTunes Store request.

The network connection timed out. Make sure your network settings are correct and your network connection is active, and then try again. I ran diagnostics; It said Network Interface Verified, Internet Connection Verified but secure link to ITunes store failed. I do not know what to try.
I have made sure everything is up to date, restarted everything.
Can anyone please help me what should I do?
