My friend can't run ranked servers becuse none of them are available to enter! How it can be solved? He has the required content!
What's his rating and reputation? If he never raced on ranked before, don't use "Only eligible" checkmark, it might not work correctly for first-time drivers. You start with 1500 rating and 70 reputation, so try each ranked server one by one.
Well, the biggest surprise is that he has 0 rating and 0 reputation! He managed to connect to ranked server. Seems like something was wrong with the server... sorry for bothering
That's because he has never driven on ranked, the system doesn't know his numbers and puts 0s there, but that's incorrect, his actual stats were 1500/70.
