Currently the problem is under observation.

I think its a bug in your SDK. If server response answer to the Firmware Query with method HEAD and/or GET comes to fast it produces boot sector erase (attached log).

I made changes now on server script. I added command 'System.Threading.Thread.Sleep(8000);' to my server script. Result is a delayed answer. And now it looks very promising that the problem is fixed.

Are you sure you selected the correct flash memory map during all the steps of building and programming the firmware?
Which update function are you using? The one provided by Espressif for FOTA or a custom one?

in some cases the SDK Firmware Update still clears the boot sector.
Its documentated in the debug-log

Devices are soft bricked then and need service.

May be a low memory problem?

Attached is a log.

Iam on latest SDK, non os.
