ClearPass Authentication failure Error 204



i have to configure guest wifi access with ClearPass Captive portal.

i have configured 2 VLANs(internal corporate and guest), made SSIDs. and i have working internal WLAN and Guest internet.

I used this link for confiruration of captive portal.

After i connect my device to wifi AP it forward me to IP addess of clearpass guest portal. I fill in the user name and email and after clicking login it forward me back to registration page.

At the access tracker I see that i have "no service match and error 204".

I have configured only one service - Controller Guest Service Guest Access.

Please help. How to configure correctly captive portal authentication?

Look in the service rules for the service and see which value is not matching.

Re: ClearPass Authentication failure Error 204

in the service rules i found 3 rules.

the third seems was created when I added the service..

i don't know what to fix here... SSID is ok. Radius authentication is also..

Re: ClearPass Authentication failure Error 204

  • Have you mapped proper authentication source in service rule?
  • Are you using posting https or http request? If you dont have proper CA certiifcate installed , try disable https option in guest page
  • Do you have CA certificate intalled on controller/CPPM?
