Thanks for the log file. Unfortunately nothing suspicious here. We ask your camera TEC to move to -15C and that's it (from the SGPro side). The next step here is to understand the camera's side of the story by finding the camera ASCOM logs. It might have more details. If nothing has changed with respect to software... SGPro, ASCOM, Camera drivers, etc and you see things broken where they where once working, you might want to check stuff on the hardware side (especially if it is cold where you are). USB stuff tends to fail much more quickly in extreme cold. Hubs and stuff like that was made for indoor use. Power supply voltage, solid connections, all that stuff.
