Unable to complete an upgrade finder request

Snapshot ID is in 814a0b949ad544189cbb98884efd9f6a
I am able to run upgrade finder prior to the raid on Nitemare on Aerie Peak - US

Could you give me a little more detail about your issue? Which particular Upgrade Finder search isn’t working for you? Does it give an error message? I tried your snapshot with several Upgrade Finder searches and they all seem to be working fine.
