QSslSocket vs QTcpSocket problem

[camol]

Modified server1 code:

Modified test server2/client code: (removed)

I'm having trouble uploading through using SSL, a situation that in early server1 sends some 8842 bytes, and the server gives a two bytesAvaible just exactly what 4096 means that the code can not go further in the next step bytesavaible gives some 4,044 bytes, and therefore all dishes are made from the second turn, do-while loop. Previously, I managed to write a version without SSL (which is, however, I needed) and everything worked perfectly as I wanted to send no matter whether large or small files and in different quantities. Servera1 without ssl code:
(removed)

server2/client without SSL:
(removed)

I've changed in server2 signal readyRead to encrypted in connect, becouse it was my mistake, but after that I can't get out from first loop becouse bytesAvailable gives 0 bytes and I don't know. Thanks for the help in advance.
