Wi-Fi Connection Issue with Farmbot

Farmbot was previously connected to a hotspot, but it is no longer connected. I reset the system, and now the blue and green LEDs on the Farmbot are no longer blinking.
What could have happened? What should I check?

Is it possible that the device overheated and I should wait before turning it back on, considering I’ve been working with it for over 8 hours?

Maybe try flashing the FarmbotOS for your hardware model onto a new SDHC card and re-configuring your bot.
