What is wrong with my Cyclone II configuration circuit?

Hello

you can not download .sof file into eeprom.

as Galfonz says, you need to convert your sof-file but into jic file.

pof file is the file downloading into EEPROM directory.

but your circuit does not seem it has the socket for writing eeprom.

so, in this case you need create jic(JTAG Indirect Configuration File) file.

this file is downloading file (to eeprom) via JTAG.

since I don't have time to write detail.

I give you a hint. see attached file.

see you.
