3661792 - SSSLRC_CONN_CLOSED error logged on the Dispatcher trace file

An ABAP instance does not fully start.

The Dispatcher process remains in "yellow" state and the following entries are written on its trace file (dev_disp):

[date and time]
  SSL_get_state()==0x2120 "TLS read server hello A"
*** ERROR => SecuSSL_SessionStartNB(): incomplete initial SSL/TLS handshake [ssslsecu.c   6551]
*** ERROR => NiISSLStartOnClientConn: SapSSLSessionStartNB failed (-10, SSSLRC_CONN_CLOSED) [nixxi.cpp    11123]
*** ERROR => MsIAttachEx: NiBufSSLStartOnClientConn failed (NIESSL_CONN_CLOSED) [msxxi.c      1595]
*** WARNING => Cannot connect to message server due to an error in the SSL layer. Check your SSL configuration. [dpMessageSer 1947]
DpUpdateStatusFileWith: state=YELLOW, reason=Server not attached to message server
*** WARNING => DpMsAttach: failed to attach to Message Server (rc=-43) [dpMessageSer 1981]

At the same time, the Message Server trace file (dev_ms) is not updated (which is a key symptom of the scenario addressed on this KBA).
