Competition server problem

I can only go into competition server on v1126 (on v1128 tell me competition servers are off) , but later if I want to connect to OWC server (Tatuus) - I cannot because server is v1128.
SO, how to take part in competition????

 

The servers and CS all run on 1128. Are you sure you use "none" in beta?

 

ok, I had v1128 version Release Candidate. with none selected is working , thanx
