iPod Touch 5th generation; iMessages and Facetime doesn't work I recently got my iPod Touch, and a couple days ago, I was signed out of FaceTime and iMessage (not by my own doing) and I haven't been able to log back in.
I have already tried changing my DNS to 8.8.8.8 and 8.8.8.8, 8.8.4.4, I have logged in and out of my Apple ID on my iPod Touch, I have changed my email address and then changed it back, and I have used a different WiFi connection.  The message that pops up (after it fails to log in) says, 'FaceTime Activation Could not sign in.  Please check your network connection and try again.'  This happens for iMessage, as well.  I am using the right password and email, and I do not use an iCloud account.  What should I do to be able to log in again and keep my email the same?
I will try restoring the iPod itself. It sounds like a software issue, maybe about cache.

There's also another possibilities about your network routers. It might be blocking those ports or whatever. Try with an Apple one.
