• Post-license modification on the vCenter, VMware Live Site Recovery initiated a mandatory validation check. Due to a communication breakdown between the VMware Live Site Recovery host and vCenter SSO, the validation process exceeded the 300-second timeout period, resulting in a ConnectionDownFault and subsequent plugin failure.
