The error message is being returned from our API, so it's not a
whitelisting issue. It sounds like either the version of Gravity Forms
you are using doesn't support or datacenter stuff (unlikely) or you
have an edge-case setup they hadn't considered. I don't know how it
works at all, but it could be that you have accounts in multiple
datacenters, it allows you to use multiple accounts, but they are
setting the datacenter for the whole plugin based on a single api key.
You should talk to them about that and provide a link to this thread.
