Hello. I just got a used Steve's LED setup for my biocube. It has the Bluefish controller. I loaded the app on my Samsung S21 to configure the controller and I get so far as to SEND BLINKUP, I then get the countdown screen. It just says 3 on the screen and a message flashes at the bottom "Server Is Not Trusted". I have unloaded and reloaded and nothing helps. I do it with wifi on and with wifi off, same results. Any tips?
