what kind of errors is that? How can they occur? Reception or Transmision? What might be the cause?

Both these error codes, 75777 (0x12801, ERROR_SSL_UNEXPECTED_MESSAGE) and 75778 (0x12802, ERROR_SSL_BAD_RECORD_MAC) are returned if badly formatted SSL/TLS packet was received. Bad record MAC is returned if the MAC checksum does not correspond to the packet data.

These errors can be returned by both local and remote sides; please use the Remote parameter of the OnError event to track the party that invoked the exception.

To bring this to a positive end: It was a multithreading issue. The Send API was called simultaneously from two or more threads and not prepared to be locked. It is now and everything is fine.
