There was an error connecting to the Apple ID server. Windows 10.

I have Windows 10 on my pc. I have the most current iTunes and iCloud updates as well. Ever since the most recent update, I am unable to sign in to any apple accounts from my desktop computer. I can sign in without problems on my iphone and ipad, and the online icloud. When I try to sign in through the desktop itunes program or through the icloud for windows program, I get a pop-up window that says "Verification Failed" - "There was an error connecting to the Apple ID server." I have tried restarting my computer, uninstalling and re-installing both programs, I have tried changing my apple id password. Nothing seems to work. Please help! Thanks!
