SCOM 2012 R2 UR2 - Discovery is in progress.... never ending

Hi

I have

one SCOM2012 R2 CU2 server = SCOM1

one DB server with all DB on it = SCOMDB1

One server with SSRS + Web Console installed = SCOMRS1

problem 1: SSO to web console doesnt work

problem 2: When I try to discover new servers in order to install a client via the SCOM server, The Discovery process is in progress and never ends.

The SQL Server Service Broker is up.
