3715227 - TLS / SSL certificate errors in SAP systems

There are one or more of the following errors in SAP systems, traces, or logs:

• received a fatal TLS certificate unknown alert message from the peer

• ssslerr_no_context_yet

• SSL handshake failures during RFC, HTTP, HTTPS, or ICM communication

• Connection termination without a clear application-level error

• SSL-related short dumps or trace entries in dev_icm, dev_w*, SM21, or network traces

These errors often lead to confusion, as similar messages can appear across multiple components and communication scenarios.
