Glad you found your problem. Both methods work. We tend to use Active Serial as you are doing, or use passive serial or passive parallel modes, if we have a CPU that has the flash storage to hold the bitfile.

They all work. Everyone has their preference. We tend to not install the headers in production and use a bed of nails approach. If the header sizes are a problem, we have used custom headers as well, with a breakout board, or bed of nails setup to access them.
