Imessage error
Recently my imessage signed itself out after I rest my Apple ID and when I tried to sign back in it doesnt work. It asks me to put in my Apple ID details and when I do it says "An error occurred during authentication" in red down the bottom. I know that my details are correct as I have tried a few times and made sure that everything is right, I have even made a new Apple ID yet it still doesn't work.
i would just like to know whats wrong and the steps i can take to fix this.
thanks
