There are two issues that are not visible from the artificially truncated(!!) error details that you quoted initially.
(1) you originally had configured your client to use "SSL client Anonymous" (SAPSSLA.pse)
(2) you're talking to a defective TLS Server which is sending a malformed TLS Certificate Request handshake message with an empty certificate_authorities element, in violation of the TLS protocol specification, and you had not enabled the workaround to blindly send a client certificate in response to a malformed CertificateRequest handshake message. See SAP Note 510007 section 7.(ssl/client_ciphersuites=208:HIGH:MEDIUM:+e3DES).

PS: The amount and intensity of random guessing around here is disappointing.
