I have installed "System diagnostics" tool on the AOS server machine and made all required pre-configuration tasks, but the tool is unable to connect with the LCS web-service. (I have followed all the installation steps provided by Microsoft https://docs.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/lifecycle-services/ax-2012/install-run-system-diagnostics-lcs )
The discovering the AX environment step works fine. The problem occurs during the “Upload environment” step.
Here is the error from event log: "Web Service Call Failed: An error occurred while making the HTTP request to diagservice.lcs.dynamics.com/externalservices.svc. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server."
Any help would be appreciated.
Please ensure the system can use TLS 1.2 to connect to the LCS web services.

Hello,
Thank you for your advice. Regarding this link Windows Server 2012 R2 natively supports TLS 1.2 for client-server communications over WinHTTP, but as I have verified in my case the value of the efaultSecureProtocols registry setting is empty. I'll follow this procedures to enable TLS 1.2 on client.
Please ensure the system can use TLS 1.2 to connect to the LCS web services.
