iTunes store is not connecting

I'm getting this message:

"iTunes could not connect to the iTunes Store. The network connection timed out."

"Make sure your network settings are correct and your network connection is active, then try again."

After running diagnostics, I saw that the Network Interface and Internet Connection Status were both good, but not so for iTunes.

I flushed the DNS Resolver Cache, and am still not able to access the iTunes store.

Is anyone else having this problem and what can be done to resolve it?

Thank you.
