I've been getting this error a lot, more so now that Beyond Light came out. Before, reinstalling it would work, but only for one or 2 play sessions then it would give me the error again. I tried flushing my DNS and resetting my networking stuff, that didn't work. So I uninstalled and reinstalled, that also didn't work. When I did reset my network, I managed to actually get a code: nightingale, but that told me to reinstall the game, which I did, and now we're here with no solution. I don't know where to go from here. I managed to play Beyond Light twice since it came out, despite trying to launch it many times.
