Can you use system-console to talk to the Nios? - Using system-console can help to see whether the system is in reset or not.

Is the Nios reset output connected to Nios and its peripherals in Qsys? This is used during nios2-gdb-server --reset-target. You can try remove the --reset-target and just performed the nios2-gdb-server connection.

Can you manually load the software after the sof file with memory initialization configured into the FPGA (If this works but direct nios2-gdb-server doesn't work will be weird)?

Do you have external push button reset connected? Maybe you can try push the button and see.
