Flotilla Rockpool will not find my Dock


I have tried so many options like downloading Flotilla Offline, re-downloading everything, rebooting, changing Micro USB cables, reflashing the firmware and it still says it can’t find my dock.
Also, (these are sub-important things) When I try to manually put in my IP address it just changes back to and every time I load Rockpool it shows a flash of the main page then says it can’t find my dock.
