Hi,
First of all, make sure your PC and Arduino connected to same WiFi. Perhaps you can attach some screenshots of Arduino Serial Monitor here for easier troubleshooting.
Secondly, try pin 10 for RX and pin 11 for TX for your program. Using pin 0 for RX and pin 1 for TX might cause some problem because it crashes with your Arduino Serial Monitor display.
