Question about using Dicom TLS with HOROS

I’ve been playing around with the DICOM TLS setup for Orthanc again, and it seems that it works now between Orthanc Instances based upon the Connectivity Checks when I check the instance interconnectivity using that.

I’ve always had trouble getting HOROS to work using TLS, but may have made some progress.

The error that I am seeing in the Orthanc log when I ping it from HOROS shows:

E0625 20:35:06.346480 CommandDispatcher.cpp:284] Receiving Association failed: DUL secure transport layer: unsupported protocol. It is the same error with using an anonymous vs. certificate from HOROS and with verify peer on or off from HOROS. I suspect that the failure has something to do with the openssl library on my Mac or on HOROS and not with Orthanc. Just wondering if others have had success settting up TLS with HOROS.

I am running an older Mac OS version, and it shows this:
