Description

I have a more complex project. but to make it simple I am testing only the "OnDemandConfigPortal" Example. It works Good on Android but not on Windows 10. I tried disabling the firewall without luck. when I connect to the AP from the PC I see this debug message more frequently

dhcps: send_offer>>udp_sendto result 0
dhcps: send_offer>>udp_sendto result 0

I think those are not errors because result 0 is the LWIP ERR_OK sometimes when i connect to the AP. it redirects me to msn.com but then when i type the IP (192.168.4.1) on the browser I get no response "ERR_CONNECTION_TIMEOUT" then the output in the serial terminal is 

*WM: [3] -> www.msftconnecttest.com 
*WM: [2] <- Request redirected to captive portal 
*WM: [3] -> www.msftconnecttest.com 
*WM: [2] <- Request redirected to captive portal 
*WM: [3] -> wpad.mt.local 
*WM: [2] <- Request redirected to captive portal 
*WM: [2] <- HTTP Root 
*WM: [3] -> 192.168.4.1

when I type ipconfig on windows cmd. I find that it gets an IP from the AP

Wireless LAN adapter Wi-Fi:
   Connection-specific DNS Suffix  . :
   Link-local IPv6 Address . . . . . : fe80::1c0c:5a92:c42f:6a4e%3

Before opening this issue. I tested CaptivePortal Example from ESP32 Arduino SDK examples. it didn't work for windows but worked on Android. I though it might be related so I put a comment on this issue reporting the problem. I got the suggestion to open a new issue here though.

Thanks a lot

I'm running into the same issue. Hope this can be diagnosed!

check firewall

amrlsayed commented 5 years ago

Hi Shawn, I disabled the firewall but same problem. Do you mean it's working good with you on windows and the problem would be our environment such as Firewall ?

tablatronix commented 5 years ago

No, windows 10 firewall can block captive portals

connornishijima commented 4 years ago

It doesn't work on a Galaxy S8 running Android 9 (Pie)

iw2lsi commented 3 years ago

same problem here... on Windows 10 the captive portal is not opened... and the connection is not established; seems to works on iOS.

tablatronix commented 3 years ago

Try without firewall ?

iw2lsi commented 3 years ago

Hi,

yes... firewall was not enabled...

It has been awhile since I last used windows 10, have you disabled other network connections ?

iw2lsi commented 3 years ago

Hi Shawn,

that's a good point... I have a wired network too... I'm checking it right now...

Hi...

no... it does not work even with the wired card disabled... this is the log... could it just be a timeout problem ?
