OK, I've tested against a default SdkConfig and it still fails.

Shubham, what are you using as the provisioning client?
I'm getting non-deterministic results and only extremely rare successes using the ESP-IDF SoftAp Provisioning Android app.

It's almost certainly a non-default sdkconfig because I am trying to resolve this within an existing project. sdkconfig: https://gist.github.com/william-ferguson-au/4990482c23de7df5969ce47bef8ea266 Note: my main issue now is that the results are non-deterministic.

Provisioning starts Ok, but when I use the ESP Soft Ap Provisioning App from Google Play to connect to the AP it fails with I (868) wifi_prov_...

Solved.

I had neglected to create the default_wifi_ap prior to provisioning.

Done https://github.com/espressif/esp-idf/issues/6091
