Update: Server client working together, but still ESP8266 can not receive from arduino. Need serious fast help. My project's last date is near.
It's nothing about special code, program logic works. But even a simple serial echo program dosen't work.
Baud rate tried 115200, 19200, 57600.

To diagnose and figure out where is the issue, you can still use your USB-TTL by connecting RX only, on the Arduino TX and then on the ESP TX to sniff the communication between both.
That will help you to figure out who is not talking at proper time.

Both are transmitting well. But ESP dosen't receive for some reason. This is the problem.

What firmware are you using on ESP ?
If it is AT firmware, beware that every commands requires both CR+LF, not only CR.
