To understand the original traces on each side of a circuit board, you can put a powerful flashlivht on the back to see through.
I can’t say if the hole is too wide and makes a short circuit with another close track.
Do you use flux ?
Have you cleaned the track with water on a coton tip ? (To remove battery leak) What kind of soldering wire do you use ? Shitty soldering iron does not stick.
I had the same issue with a circuit. Gently sanding and using flux solved my issue. But it was an ugly soldering. I am not proud of it. You are not alone.
