System Center Orchestrator not working with TLS 1.2

I was running Orchestrator 2016 Update Rollup 4.

I have followed the documentation on how to set up the TLS 1.2 in the orchestrator environment (https://learn.microsoft.com/en-us/system-center/orchestrator/install-enable-tls?view=sc-orch-2019) and upgraded to Update Rollup 8 and completed all the other various configuration changes. After completing the steps, I still cannot make a Rest API call using the Rest Integration Pack. I'm receiving the same error message as before upgrading (see below).

I'm using Wireshark on both ends of the communication and do not see any attempts at sending connection information using TLS 1.2 from Orchestrator. Does anyone know if the Rest Integration Pack complies with the system settings enforcing TLS 1.2 to be used?

ERROR

The underlying connection was closed: An unexpected error occurred on a receive.

    Hi @Shawn Proskin ,

    System Center Orchestrator fully supports TLS 1.2 after being configured to do so, however I don't believe (not 100% sure) the REST integration pack has been updated to support TLS 1.2.
