Hi there, I really need help.

I'm using DoIt ESP32 devkit V1 wifi + BLE board with Arduino IDE

Problem

• I'm trying to connect esp32 to my wifi network in station mode and it connecting and also provides the ip address but when I'm trying to open to the the ip in browser it's showing 404 error when I'm in same network.I have tried to use other browser but it didn't help.

serial monitor result.

This problem is only on station mode
I tried to check my wifi router clients but it also showing up the esp32 there.

It's puzzeling me up that it connected and served the page for the first time in that network but from the next day the issue showed up and I didn't even changed the code. it's really confusing.

The first and second images show different ip addresses .
Try the address shown at the top of the second image , the one that works .

The ip of your device is also a bit strange - but that’s another issue

[tirtharajsinha]

the Ip address is diffrent because in the first image I'm trying to connect to my home wifi network and in the second image I connected to my mobile wifi network. two Ip are diffrent because thay are in diffrent network. I hope It's clear to you
