Delphi 10.4: Indy zerschreddert?

[idontknow]

Ja, das klingt sehr ähnlich. Bei RSP-29074 scheint der Server das Problem zu sein, bei mir glaube ich eher der Client:
Wenn ich die Aktivitäten des Clients (Connect, WriteLn) auskommentiere und stattdessen mit OpenSSL.exe connecte, dann kann ich eine Verbindung zum dem IdTCPServer mit SSL aufbauen:

OpenSSL> s_client -connect localhost:3333
CONNECTED(00000180)
