Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/182

int connRes = WiFi.waitForConnectResult(); // might not return

this might hang in an endless loop

while(status() == WL_DISCONNECTED) {
    delay(100);

}

So it will never switch to the config mode.

Not sure, if this issue was reported already

To be fair: I´m not sure, what the ESP8266 does in the background and when it will report Connect_FAIL
In this case the visualmicro debug mode was the root cause. In general strange conncept from ESP8266 Wifi lib to loop a poll, if there would be a defined timeout of the connection attempt. (if so, ??)
A callback sounds for me more reliable.
-> great thank to the autor of WiFiManager,
