Hi

I tried to set IP, GetWay, subnetmask and also SSID, Password in portal. but All IP's set to 0.0.0.0
How can I cope this issue?

Thanks in advance

hmm, I think you will need to reconnect to apply the new ip. But they will be gone again if you reboot, you will have to save them in flash(littelfs) and load on boot

I like to say, befor using ESP32, I used ESP8266 and it hadn't any problem and worked well!

Ok why is your connection failing though? Looks like wrong password

There is something else going on here,

Let me figure out wtf is going on, looks like an esp bug

This is wrong.

saveParamCallback

  wifiManager.setSTAStaticIPConfig(WiFi.localIP(), WiFi.gatewayIP(), WiFi.subnetMask());

you should be passing in the parameters here, but wm does this on save automatically for staticip params, so just delete this line or the entire callback
