Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/291

I have been writing some code for the esp8266 but it was messy so I decided to use your WiFi manager library. It run through the autoconect and connected to my WiFi router. It gave me the IP 192.168.8.104. But when I connect to that it says page can not be displayed. I tried to ping it but nothing. OK I thought and went back to my original working but messy sketch and now that say the same thing too.
I then uploaded the example webserver for the ESP and again the same result. What am I missing?

hi, you might have some flash corruption although i haven t seen that ip pop up until now

try a WiFi.disconnect()
you might also try flash erase config from the sdk
check kentaylor's flash erase and see if it helps

cheers

j = 63
addressSucceed: 258048 - 0x3f000

Exception (0):

Thank you guys. Although that did not work it did set me on the right track. In the end I used the esptool to erase the firmware. All working now.

esptool.py --port /dev/ttyUSB1 erase_flash
