Actually spent a bit more time on this today playing with LNBits with LNDHUB Extension enabled. I can import this into BlueWallet app however that imports a wallet with umbrel.local in the path which only works on wifi, when I access my umbrel via tor and create a wallet there and enable an LNBits wallet with LNDHUB I can’t add it to BlueWallet I get the same error as trying to import the ones in the initial post. I feel 90% sure the underlying issue is ability for BlueWallet to import a lightning wallet via tor on umbrel.
I also have tried manually starting the tor daemon in the app and that failed, maybe zeus is the safer option after all.
