If connecting with store bought patch cables works, and the ones you made doesn’t then the problem is with the cables you made. One or more of the pins aren’t making contact correctly. The only solution to fix the cables is to cut off the ends and try again.
Making cables is tough. There’s a reason that most people don’t bother trying it them selves.
I would look at the cables again, and check them using a digital multimeter for connectivitiy.
