After laster update on January 30, dedicated server is not allow anyone join to the server when "serverControl: false". Users are dropped off from server, there is no way to create a lobby.
I had to rollback Dedicated Server Version in order to keep creating my loobies. Please, this looks serious. Also, CURREN_SESSION attributes does not have the track list for Automobilista 2, it is the same track list of Project Project Cars 2. I had to make a workaround with JQuery to replicate track list from NEXT_SESSION panel.
