"but not succeed on Windows" - what do you mean?
What doesn't succeed?
What debugging have you done?
Have you got a packet capture?

And most important, do you get an error message on the client?
What happens if you browse directly to the guest portal IP in the browser?

When I connect to the SSID, it appears the link:

https://192.0.2.1/fs/customwebauth/login.html?switch_url=https://192.0.2.1/login.html&ap_mac=70:b3:17:96:50:60&client_mac=d4:3b:04:78:4a:8d&wlan=Test&redirect=www.gstatic.com/generate_204

Picture is attached. I have tried to turn the firewall off, but it's no use. Otherwise, it works perfectly on Iphone and Android.

"What debugging have you done?" What command should I use to get the information? I check the message logs, but it seems to show nothing.

Thanks in advance!

Best regards

And what happens if you click on Connect in the image you've attached?
Please also include the URL bar in the next image, I'm curious if the browser trusts the certificate (I guess it doesn't).

When I press connect, there's nothing happen! Also, I don't receive any error message from client.

I have try http (or) https:// 192.0.2.1/login.html, but look like can't connect. Always the picture like above appears.

At last, my problem is solved. It is caused by Chrome Browser. I change to Microsoft Edge, and the login page appear.
Further more, can anyone tell me how to solve this problem on Google Chrome?

> can anyone tell me how to solve this problem on Google Chrome?
Well you need to answer the questions people have already asked you and/or provide the screenshots requested.
As Pat suggested this could be a certificate problem.
Have you installed a proper certificate on the WLC which can be verified/trusted by Chrome?
Also www.gstatic.com/generate_204 is the Google/Chrome captive portal detection URL and if you actually get redirected to that after login it might seem like nothing happened but all that URL does is deliver a 204 response with a blank page.

Yes, I haven't installed the trusted certificate which is verified by Chrome. And that's my problem.

Besides, I am choosing to disable https because it maybe convenience to me. The web authentication works with all browser without any trouble now!

Here is the command:
(WLC)> config network web-auth https-redirect disable
After that, reboot the controller to get this command to work.

Thanks all for helping me to solve this trouble!
