Is Discord perhaps blocked on your network or unavailiable? That would be the first thing that comes to mind.
There may also be a restriction to actually joining the discord like your account has to be X amount of days old or need an email verification. Don’t think it’s this one as it would still at least connect as far as I know.
Also I think you need to be witch or higher to gain access to the discord in the first place so you might want to wait for that
