Hi.
Delete the software and create it one more time. If it doesn't help regenerate nios2 system and recompile Quartus II project, then create your Hello world software. I face the same problem from time to time and don't know another way to solve it) Have a nice day. - Altera_Forum

Thank for help
I recompile software, hardware many times, but i get the same problem. I install "Altera Quartus Usb blaster" by creating /etc/udev/rules.d/51-usbblaster.rules: # Altera USB-Blaster rule to set mode to 666. SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ATTRS{idVendor}=="09fb", ATTRS{idProduct}=="6001", MODE="0666", NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}", RUN+="/bin/chmod 0666 %c" - Altera_Forum

Can you check that FPGA is successfully configured? For example, leds start blinking or conversely stop blinking
