That's good you're not banned. Have you tried uninstalling and reinstalling the game?

I kept that as a last resort
quick question unfortunately im from iran did ea recently band us ?! because i cant connect to the titanfall 2 either

I don't think EA banned Iran. I did find this YouTube video of a few more things to try if the reinstall doesn't work.
