We see this from time to time, and are not sure what the reason is. Could be some setting in the Wi-Fi router that prevents, or could be latency / timeout during the download process.

Since you are on ESP32c3 I assume this is your own hardware. And then there is an other potential issue: Power consumption. The ESP consumes more power while downloading compared to normal operation, as there is continuous Wi-Fi activity over a relatively long time. Is your power supply sufficiently stable?

There two other ways to upgrade:

• USB port
• UART

In both cases, you can follow the guideline in the Firmware User Manual, chapter "9 Flashing the device over USB cable".

Solved. Power consumption was the Problem! Tryed with stable power supply and it worked.. Tanks for your support.
