Select Tools > Processor > ATmega328P (Old Bootloader) and then try uploading again.
Well..I might be able to help you, I am also working with Chinese Atmega328P-AU ICs. Can you please check these?1. Does the IC successfully upload bootloader via ICSP?2. Does the Reset line normally stays high, and goes momentarily low just after 'Done compiling' shows up?3. Do the FT232RL IC respond to loop-back? Your schematic is okay for normal application, but I would suggest you to upload your own bootloader, since, most possibly, the bootloader has got corrupted. Try MiniCore ATmega328P with 16Mhz external crystal and BOD at 2.7V as the bootloader, and select board as UNO, not NANO.
