I flashed RAK2245 image file in LPWAN Gateway, and configure it, it started connected to WiFi and started receiving lora packets from end node and sent/receive from TTN server as well. After some period it stops connecting same WiFi. So I formatted the SD card and tried to put back new gateway firmware image file in SD card. But I’m not able to flash it saying error–>Something went wrong. If it is a compressed image, please check that the archive is not corrupted.

Any solution for this. I tried to run application as administrator as well but showing same error.
