the rockpool/flotilla daemon you are in effect using this way are not compatible with the latest firmware, the one found in the pre-repo. This could be the problem if you successfully flashed it trying to get things to work initially.
You need to either switch to the 'shipshape' level on all front, as per 'pre' (somewhat succinct) instructions, or re-flash the original firmware using the 'upload' script that you should find on your system under ~/Pimoroni/flotilla/flotilla-offline.
