I'm having a weird problem where i cant upload my design to the DE0-NANO board, gives me the weird error message which is the title of this question.
Any other design uploads fine and I have done nothing different. Restarted the computer, rewrote the project, checked if the correct device is chosen and updated all the drivers, still doesn't upload.
Any suggestions?

Problem solved. I named the .sdc file differently from the name of the project. Creating a new one with the right one solved the issue, not sure why, but here we are.
