If you are having problems joining the server, that is, you join as an spectator instead of a driver, try switching to another team when selecting your car, then try to rejoin the server again. If it works, switch back to your correct car.
This seems to be a problem with rFactor 2, not the server. We've been running the same configuration all year long and yet we get different behavior. We've created an issue in isiforums.net regarding this.
