In a previous reply I mentioned that I recalled that there were some diagnostic enhancements for AT-TLS in z/os 2.5. They are described in the z/os 2 .5 education articles on GitHub :
https://github.com/IBM/IBM-Z-zOS/blob/main/zOS-Education/zOS-V2.5-Education/IEAV2R5%20Communications%20Server.pdf If you are fortunate enough to have z/os 2.5 and use the default trace level (2) you should see additional information about handshake failures and more detail with level 8.
