its a cloud app that you previously configured and now that you reset the hub it is still trying to connect with the hub but there is no driver for it to connect to.
No, it's definitely a local app. Maker API is one possible app (it uses this endpoint; there may be other), so anything you set up previously using that would be a good place to start.
Right. You configured something outside the hub that is still referring to an app you no longer have. The solution is to find that external thing and stop it.
