We have ivy at the front of house that seems to by dying off over the past 12 months. About half the leaves have now gone and the wood looks dead. There is white stuff all over the branches of it, but I can’t tell if it’s like a growth or pest. I have photo’s attached to show.

It looks more like a pest but aphids or mealybugs are more common on soft stems and leaves. Have you tried spraying with a garden hose to see if they fall off? I would try that first, then if many still remain, use a pesticide or Neem oil, since the infestation is large.
