Color sensor TCS34725 with PHPoC shield P4S-348

Hi,

As I'm newbie with Arudino and PHP, I fell into the following issue, while trying to establish the connection on the website with the PHPoC.

All wiring and configuration have been made as per instructions in this tutorial:
https://create.arduino.cc/projecthub/khanhhs/arduino-have-fun-with-color-sensor-5bafff?ref=tag&ref_id=sensor&offset=57

This is what I get in Chrome console for debugging:

remote_color.php:68 WebSocket connection to 'ws://192.168.75.104/color' failed: Error during WebSocket handshake: Unexpected response code: 404

Let me know what you think about this.

Thanks a bunch

404 means Page Not Found.

What happens when you follow the Arduino testing instructions in that tutorial:

Testing
Click serial button on Arduino IDE to see the IP address.
Open web browser, type http://the_ip_address/remote_color.php
Click connect button and test it.
