  1. I'm getting "Invalid nonce" error

    Usually happens when running a different implementations of the client API with the same API key. Different implementations might use different nonce generation strategies. One client could generate higher nonce and after that another client could generate a lower value, but it must be always higher then any previous nonce for given API key. To fix the problem generate a new API key. If you want to use different implementations interchangeably, keep both keys and let each app use its own key. For more info about nonce generation see: https://github.com/timmolter/XChange/wiki/Design-Notes.
