Hi.
Are you using SPIFFS or LittleFS with your webserver?
If so, did you upload the required files?

Additionally, if the wi.fi connection is not strong enough, the board may not be able to send the data to build the web page.
Or, there is a problem with the sensor and the code is stuck trying to read or initialize the sensor.

Regards,
Sara

I can still ping the board, so I know the wifi connection is still there.

Hi.
You need to change the code to use those specific pins for you board.
You can check our I2C tutorial to learn how to do that: https://randomnerdtutorials.com/esp32-i2c-communication-arduino-ide/#3

just found your answer to a previous question and your guide to fixing it and the IC2 scanner – even though the pinout on the Waveshare shows 6&7 (https://www.waveshare.com/wiki/ESP32-C6-DEV-KIT-N8) it was still pins 21&22. still need to test the CYD though

I can connect a 1 wire(DS18B20) fine

The BMP works fine on a Nano

Your problem, you have a lot of problems, Chinese products are very good.

The module can run with 3.3V or 5V.
