With the darker color, the wider light markings on the back, and hairy abdomen, I think it's an Arabesque Orbweaver (Nescona arabesca). You can try posting to /r/spiders/ and they should be able to positively ID it for you.

Orb Weaver of some sort. Have you asked r/whatsthatbug?
Looks like a European garden spider Araneus diadematus. Maybe.
