PC Web browser redirecting to https://www.msn.com/en-xl/?ocid=wispr&pc=u477 about captive_portal HOT 7 OPEN

Do not change HOSTNAME to any IP, leave it as is. This is the URL that you want to see in the browser bar when connected. It is used for HTTP redirection.

Thanks @drzony. No difference when HOSTNAME changed to yahoo.com again redirecting to msd.com.
Problem is in:
Serial.printf("Access Point started, IP: %s\n", WiFi.softAPIP().toString().c_str());
web_server.on("/", HTTP_GET, [](AsyncWebServerRequest *request) {
if (!redirectToCaptivePortal(request)) {
request->send(200, "text/html", HTML);
}
});
ERROR:
Access Point started, IP: 192.168.4.1
E (6229) event: mismatch or invalid event, id=63
E (6230) event: default event handler failed!
Got domain 'msftconnecttest.com'

from captive_portal.

E (6229) event: mismatch or invalid event, id=63
E (6230) event: default event handler failed!

Those are errors from lower layers, I can see them too on my setup and it works (They are more like warnings)
What do you see when navigating browser to http://wifi.manager.net or http://192.168.4.1 (leave HOSTNAME as "wifi.manager.net")
Is WiFi your only connection?
Is it working on your phone?

from captive_portal.

First PC Browser (chrom) shows http://www.msftconnecttest.com/redirect then redirecting to
https://www.msn.com/en-xl/?ocid=wispr&pc=u477
If I type 192.168.4.1 then Hello captive portal appears. Using phone after connect to wifi nothing happens.
The http://wifi.manager.net does not appear

Is WiFi your only connection on the PC?

from captive_portal.

If I have only one WiFi then chrom shows http://wifi.manager.net/ but my iPhone does not show.
I need to load my index.html saved on the SPIFFS or run 192.168.4.1 to load it.
If I change redirect function
//response->addHeader("Location", redirect_address);
response->addHeader ("Location", "http://192.168.4.1/" );
it works by PC but not iphone or android phone.

I have tested this code a minute ago on Android phone and tablet. It works without any changes. On other project people reported that changing AP IP address to 8.8.8.8 helped, but I have not verified it. I do not have access to iPhone or PC with WiFi so I'm not able to test it, but it should work if WiFi is your only connection and DNS address is taken from DHCP.
