Photon server and PUN 2 samples

tell a newbie please.
Installed the last server. I installed the last PUN2 in the new unit project. Set the correct connection address in the settings 127.0.0.1:5056. But when I try to connect, I get an error

Got a unexpected Disconnect in LoadBalancingClient State: Disconnected. Server: MasterServer Trace: at Photon.Realtime.LoadBalancingClient.OnStatusChanged(StatusCode statusCode) in C:\!Unity\TestPhoton\Assets\Photon\PhotonRealtime\Code\LoadBalancingClient.cs:line 2302
