Captive Portal Problem - Link

juliano_grandi — Thu, 17 Sep 2020 11:57:17 GMT

Hello, I have a problem where I can't access my institution's website (https://unilavras.edu.br) through SSID UNILAVRAS. When I place a direct network cable in this VLAN, I get access. When I try to access the site, it keeps loading the page until it fails. When I open Captive Portal, the following address appears: https://unilavras.edu.br/admin10/login.jsp which in the case was supposed to be https://atvaa019.unilavras.edu.br/admin10/login.jsp, where ATVAA019 is the name of the ZD 1200.

Any idea?

Hi Juliano,

It seems an issue with the DNS entry or the certificate NOT installed correctly.

Could you go to ZD >> System >> Certificate >> Check what is the FQDN showing in the cert.

Also confirm if you are using a wildcard cert or normal device cert.

Ping below URLs from wired network vs wireless and compare the results.

unilavras.edu.br

atvaa019.unilavras.edu.br

Hello! ok, my certificate is a wildcard certificate. The FQDN in the certificate is correct, being unilavras.edu.br, * unilavras.edu.br and colegio.unilavras.edu.br The tests for the wireless and wired network have also been carried out, and both showed the same results. Can reinstalling the certificate solve the problem?

Hi Juliano,

Before you try re-installing the cert on ZD, could you confirm what SSID you were connected to, when accessing the company's web site https://unilavras.edu.br.

Confirm the WLAN type, encryption and authentication type.

Step by step procedure to import the wildcard cert can be found here.

Share the screenshot of the WLAN configuration please.

Also confirm what is the different between UNILAVRAS vs other two SSID.

OK, see the UNILAVRAS SSID configuration:

The other SSID is a Social Media WLANS Usage and another one is not usage, only for test. VLANS is diferents too.

Hi Juliano,

This is what I was suspecting.

You are using Web authentication and seems redirection is not happening correctly or authentication is not successful.

Normal connection flow on web auth is:

UE connects to WLAN >> Gets an IP address (at this point client cannot reach internet as ZD blocks the traffic. UE is in unauthorized state) >> ZD redirects the client to web portal, for the authentication >> Client inputs username and password (In your case AD credentials) and submit the form >> ZD checks with AD if login credentials are correct >> upon correct credentials, ZD let the UE brows the internet (authorized state).

Please confirm if you are completing the above connection flow and when you are trying to access your company's website.

I also suggest opening a support case and they will help you to check/fix the issue.

Yes, the procedure is correct! When I access the network with a wifi device, open the Login Portal, and login perfectly. I browse all sites except our institution.

how do i open a support case, could you help me?

Hi Juliano,

You can log a case from the below link. However, an active support contract is must.

I hope you have purchased support contract for your controller.
