Apparently, the ESP already fails to connect to your WiFi. Double-check that the SSID and password are correct; then check that your WiFi is set to allow the new device to connect. Try to improve the WiFi signal by moving the ESP closer to the access point.

I checked the SSID and Password of my WiFi network is correct. I followed the all the instructions as you said but I am still getting the same result.

Thank you.
