So the versions are as follow: KSC 11 workstation agents: some are 11.1.1.126 and some have updated to 11.4.0.233 server agents: are all 10.1.2.996 and all of them are green and healthy KSN set to be active on all hosts Policies all in order I have a feeling that this is a problem with versions - could KSC 11 be ‘too old’ for the hosts which turned to 11.4.0.233? but i cant understand why some of the red ones are on 11.1.1.126...
