This is the expected behavior if the cell needs to be cleaned, the salinity is very low, or any other related condition which would make it harder to send power through the cell. The best approach would be to follow this complete checklist:
Ensure that the pool water's salinity is in range, testing it independently using titration-based chemical test, or else a recently-calibrated digital test. The target level is 3500 ppm.
Ensure that the cell is fully cleaned (multiple times in a row if necessary, so that when fresh cleaning solution is added there is no "fizzing"). Flush cell thoroughly with a hose-end nozzle.
Ensure that all connections and cables are fully tight, fully seated, and free of debris or damage.
Ensure that water is completely filling the Cell throughout daily operation, esp. if getting daily repetitive warnings (which typically come on later in the day, not within the first few minutes of operation).
Ensure that the controller has not inadvertently been changed to a different cell-type setting (if applicable).
Ensure that the water is within normal operating temperatures.
Powering the unit off and on causes the system to re-check itself, which will have the system run for a few minutes before any warning light displays. If a warning light triggers, then an issue remains (such as the cell requiring further cleaning, or the cell being depleted (typically years down the road).
Based on your timing, it is very possible the cell just requires additional cleaning. Since the cell is opaque, this is not always visible to the eye. Cleaning can be required on a monthly basis, or sooner or less frequent based on the pools Saturation Index level (LSI) - be sure you check this as a part of your regular water chemical balance testing.
