Description

The case is this:
My program connects to WiFi in setup by calling wm.autoConnect(...);
In loop() I check if the WiFi is connected and if not I start the configPortal(...)
While connected, I turn off my AP so the ESP disconnects and my code starts the configPortal.
A few seconds later, I turn on my AP and wait for the captive portal to timeout (I have set it to 180 secs).
According to the WiFiManager code, when the configPortal ends, it should reconnect to the previous wifi. But instead, I see in the log "WL_STATION_WRONG_PASSWORD" and don't know where it comes from.
So my code detects that the wifi is not connected and starts the configPortal again. And this loop continues forever.
