1 year ago It's the same on my end. Recently started using Wifi Manager and gets redirected to 0.0.0.0 Your workaround fixed it for me for now.
So after applying this workaround, I'm able to connect to my local network and I get an IP address. But I'm not able to start web Portal. It always redirects to 192.168.4.1 now, even if device got an IP from my DNS. By removing the fix you provided back to origin, it keeps redirecting to 0.0.0.0 again.
I used this way to get Wifi Manager to my project:
[env:esp32doit-devkit-v1]
platform = espressif32
board = esp32doit-devkit-v1
framework = arduino
monitor_speed = 115200
[env]
lib_deps =
https://github.com/tzapu/WiFiManager.gitmy code looks like this
#include <Arduino.h>
#include <WiFiManager.h> // https://github.com/tzapu/WiFiManager
// wifimanager can run in a blocking mode or a non blocking mode
// Be sure to know how to process loops with no delay() if using non blocking
bool wm_nonblocking = true; // change to true to use non blocking
WiFiManager wm; // global wm instance
WiFiManagerParameter custom_field; // global param ( for non blocking w params )
String getParam(String name){
//read parameter from server, for customhmtl input
String value;
if(wm.server->hasArg(name)) {
value = wm.server->arg(name);
}
return value;
}
void saveParamCallback(){
Serial.println("[CALLBACK] saveParamCallback fired");
Serial.println("PARAM customfieldid = " + getParam("customfieldid"));
}
void setup() {
WiFi.mode(WIFI_STA); // explicitly set mode, esp defaults to STA+AP
Serial.begin(115200);
Serial.setDebugOutput(true);
delay(3000);
Serial.println("\n Starting");
if(wm_nonblocking) wm.setConfigPortalBlocking(false);
// define some special parameters
// const char* custom_radio_str = "<br/><h3>here comes header 3 </h3><br/>";
// new (&custom_field) WiFiManagerParameter(custom_radio_str);
// add a custom input field
int customFieldLength = 40;
new (&custom_field) WiFiManagerParameter("customfieldid", "Custom Field Label", "Custom Field Value", customFieldLength,"placeholder=\"Custom Field Placeholder\"");
wm.addParameter(&custom_field);
wm.setSaveParamsCallback(saveParamCallback);
// custom menu via array or vector
//
// menu tokens, "wifi","wifinoscan","info","param","close","sep","erase","restart","exit" (sep is seperator) (if param is in menu, params will not show up in wifi page!)
// const char* menu[] = {"wifi","info","param","sep","restart","exit"};
// wm.setMenu(menu,6);
std::vector<const char *> menu = {"wifi","info","param","sep","restart","exit"};
wm.setMenu(menu);
// set dark theme
wm.setClass("invert");
wm.setConfigPortalTimeout(300); // auto close configportal after n seconds
bool res;
// res = wm.autoConnect(); // auto generated AP name from chipid
res = wm.autoConnect("smartGreenhouse"); // anonymous ap
//res = wm.autoConnect("AutoConnectAP","password"); // password protected ap
if(!res) {
Serial.println("Failed to connect or hit timeout");
// ESP.restart();
}
else {
//if you get here you have connected to the WiFi
Serial.println("connected...yeey :)");
}
wm.startWebPortal();
}
void loop() {
if(wm_nonblocking) wm.process(); // avoid delays() in loop when non-blocking and other long running code
}

Description
Problem description:
Everything seems to work, except I get redirected to 0.0.0.0 instead of the Captive Portal IP. I think the issue may have started after I upgraded to the 2022.12.2 release of the Espressif platform.
I identified the issue being at WifiManager.cpp, line 2403
As a quick hack, this worked as a work arround:
