WiFiManager: Entering wrong password to your AP = never ending lock

Wrong password in portal and you are stuck.

My first post, and I will probably piss some one off because I missed something. My deepest apologies in advance!

Hardware

WiFimanager Branch/Release: Master(?) 2.0.15-rc.1

Esp8266

Hardware: ESP-12e, esp01, esp25

Core Version: No clue… Arduindo IDE 2.0.3…?

Description

Problem description // When starting up in “portal mode” and you enter the portal, click on “Configure WiFi”, select your SSID, and enter THE WRONG PASSWORD. // Now you are stuck. A reset (button press) does not help. You have to connect to another network, then close it down do get another try. // Not possible to recover without connecting to another “valid network”

Settings in IDE, STANDARD

Module: NodeMcu, Wemos D1

Additional libraries:

// Test, is it a bug if wrong WiFi-AP-password is entered?
// When starting up in "portal mode" and you enter the portal, click on "Configure WiFi", select your SSID, and enter THE WRONG PASSWORD.
