 Recently, while applying Quality updates 39, I encountered an error stating "DVT script for service mode: AOSService on machine." Upon examining the error logs, I found the description: "ERROR: System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel." After some research, I discovered a solution: First: Abort the current process in the Lifecycle Services (LCS) as this option is only available for environments in the Deployed state.  Second: Then, navigate to the Environment details page, click Maintain, and select Rotate secrets. Choose Rotate the SSL certificates and confirm the action.  This simple solution resolved my problem.
