Any Idea What Is Causing This And How I Can Fix It ?

Question

Over night this has seem to show up on my white lace vine and is spreading quite fast. We have had a really rainey wet week here in michigan and I’m not sure if it is from being too wet? My son had his bubble machine out near this area yesterday too, could they have damaged the leaves?

I'd chalk this up to root suffocation or infection from being so wet. Fungicides might be necessary, here:
