Hi,
We are facing the issue SSL handshake is failed during step (SERVER_CHANGE_CIPHER_SPEC) client state: 12, from the below log line ssl->f_recv(_timeout)() returned 0 (-0x0000) it indicated that 0 byte were received from the server side.
This is occur in sometimes, sometime SSL handshake is success without any problem.
Just wonder that this is coming from Server side issue or client side issue ?
Can anyone help me ?
