Neither after the error happens I have to go to WoS app directly, amethyst does not auto open it if that is what you mean.

Are you using Tor for Money Operations on Amethyst by any chance?
I currently have tor disabled in amethyst.
And no other app is forcing Tor on Amethyst?
I ask because I tried to pay through Tor and got the same error.
Oh whoops orbot was forcing tor on amethyst even though I disabled it in settings I had orbot on. So now after trying again with Orbot off I am now receiving this error instead!
