Can't find the video file

I just got this message "Can’t find the video file " why can’t I access my videos? thank you

Hi, there ,
Sorry for the late reply.
Are you referring to the live feed or the video files in SD card?
If the camera is offline and you can not view live feed, try to long-press the power button for 3 second, camera will turn on and get back online.
If you mean the SD card can not be viewed, you could try to remove the SD card from your camera and then insert it in again. Or SD card did not record any file at that time due to some network issue.
