Arduino 1.6.8
ESP library 2.1 installed

Uploaded BasicOTA.ino sketch from example to the NodeMCU using usb connection all done correctly

After sone time I can see NodeMCU under ports with valid IP, when executing OTA update from arduino I am getting:
[ERROR]: Error Uploading

I conected to NodeMCU using serial port to see what is happening, I am getting IP address correctly, OTA starts and suddenly ends, this is serial console log:

Progress: 0%
Progress: 0%
Progress: 0%
Error[4]: End Failed

Any ideas what seems to be wrong

Hi DinoN,

I recently had similar issue except upload was failing each time after 2% completion.
Using esptool I have completely erased flash and the issue was resolved.

Hope this helps you as well
If you are able to try it then please post your results.
