softAPdisconnect failure, no error return

[tablatronix]

I am getting failures with softAPdisconnect returning false.

debugging
esp_err_t err = esp_wifi_set_config(WIFI_IF_AP, &conf); returns error base 11
So no error code..

Any ideas how to debug this further ?

I applied the same fix I PRed for esp8266, auth mode must be OPEN if password is empty, I could not find documentation on this but esp_wifi_set_config returns empty error before applying this.
