Npy0/nanopy difficulty

Hey there..!

I wanted to make a weekend project of sending some nano using the node RPC calls and python npy0/nanopy library. For some reason the response is always an error: "Block work is less than threshold"

Yes, I have tried increasing the work to and above the documented fffffff800000000 value.

Wondering if anyone has had luck with this library?

(Apologies for not including code or links, the anti-spam-bot erased my post when I included the amount of detail normally needed for working with other programmers.)
