Grid Legends won't connect to your servers on console "X Box"

You've uninstalled the game to reinstall it, but probably didn't download and reinstall all the previous add-ons you have before when you was playing the game, it's important you go to add-ons and look which ones you own already, that are not installed yet. Don't delete anything of what you see on this screen that is shown here, just go and look what's missing. That'll fix your problem
