We're here to help get you signed in, @checkmiout!

Is the History Channel currently in your channel lineup for your U-verse TV package? You'll need to be able to access the History Channel content through your U-verse receivers in order to use your myAT&T sign in to watch content through the app.

If it is, we recommend resetting your password, uninstalling and reinstalling the application, then trying to sign in again.

Let us know if this helps.
