As I see you are using Arrow SocKIT dev. board.
- Configure FPGA board properly ! (SOCVHPS is missed from your actually detected chain)
- Reset FPGA (try warm, hard, and FPGA reset)
- Hardware Setup -> CV_SOCKIT
- Auto detect chain
- Change file -> browse for .sof (which contains the same FPGA device as 5CSXFC6D6)
- Finally, Program FPGA
alternatively, try
Quartus -> Tools -> JTAG chain debugger -> Test JTAG chain
