Need help with assisting my backyard spinner spider with her eggsack

[Spinners friend]

Need information to help my backyard spinner to achieve viable eggsack.
Every year a beautiful spinner will live in my backyard and leave an eggsack but they never hatch.

Aww, that's sad. If that spot is too hot you could shade it with something?
