esp8266 smartconfig V2.5.4 Unable to connect to the distribution network with esptouch app

Start by reproducing the report with the supplied setup, ESP8266WiFi.h, smartconfig.h, and the ESP-Touch app. Trace the smartconfig_start callback through SC_STATUS_FIND_CHANNEL, SC_STATUS_LINK, and SC_STATUS_LINK_OVER, checking where connection progress stops. Done means the device receives the credentials and successfully connects to the router.
