Hotend shuts off during printing

Hello everyone, I encountered problems in print time. For printing, I will use the latest version of Cura + the OctoPrint plugin.
Some time after the start of printing, heating is turned off. However, printing does not stop.
Everything is fine with the hardware of the printer.

I actually have had this issue start in the past couple of days. Does anyone know why this happens? I am using a gMax2 printer with the gTouch controller Astroprint box. I am using Simplify3D to generate my gcode.
