My internet is down. Can I hotspot instead?

No, you can't use hotspot to connect Genie Client to the Server. The reason for this is that both machines need to be on the same network to connect. While it is possible for them both to be hooked up to your phone's hotspot there are multiple factors that could then play havoc with your connection. For this reason, it is not a viable option to use hotspot to connect to Genie.
