Items lost on "Lost Connection"

I suspect I already know the answer, but is there any way to recover items lost to a “Lost Connection” error? I was re-arranging my stash tabs, dropped a number of items on the ground, was moving items in the stash, and my connection dropped. Now all of the items I had on the ground are gone, probably 20-40 uniques of varying quality. If there’s a way to recover, that would be amazing, but my gut tells me I’m SOL.
