VMware VCenter 6.x Cannot find vSphere HA master agent Alarm :

Symptoms:

Cause:

Troubleshoot:

  1. Be sure that all hosts connected to DVS on cluster.
  2. Check the connectivity between all hosts and VCenter, using SSH session.
  3. Check the time on VC and PSC:

you can Login to VC and PSC using SSH >> timedatectl
