Octopus V1.1 detected but is unresponsive.

I keep getting the message "Octopus V1.1 detected but is unresponsive." whenever I try to flash my board. I already went in mainsail and set up the v-core 3 config but returned to the BTT configurator and tried to flash the firmware to the board as a final step. Fortunately the message came up and doesn't allow me to flash the firmware because Klipper isn't running on my board.
