The Cloudi-Fi Error page appears instead of your captive Portal when connected to the SSID.

When connecting to the SSID, you may encounter an unexpected error page that is different from the usual captive portal. This error page could indicate technical issues preventing proper authentication or network access.

Several possible causes may trigger this error page, including:

  • Radius requests not being received by Cloudi-Fi's servers

  • Captive portal misconfiguration (Mainly related to the Captive Portal URL)

To address this issue, several actions can be taken:

  • It is essential to check the Radius configuration and ensure it is correctly set up to send requests to Cloudi-Fi’s servers.

    • Running a Radius test connectivity from your equipment can also help identify any connectivity issues causing the error page

  • It is crucial to verify the firewall rules to determine whether the Radius is allowed

    Source Destination Port Protocol Action Comment
    Guest or Management subnet Cloudi-Fi' IPs 1812-1813 UDP Allow Radius traffic
    Guest subnet DNS 53 UDP/TCP Allow DNS resolution

  • Perform a Web Request capture in the web browser

  • Share to Cloudi-Fi Support Team :

    • The Captive Portal URL configured on your SSID

    • HTTP Capture 

    • User ID facing the error page

Following these actions, you can troubleshoot the issue causing the unexpected error page and give your network users a seamless and hassle-free experience when connecting to the SSID.

If you are still having the error page issue after following these recommended actions, please don't hesitate to contact our team (How to contact your support? ) to make the necessary changes to your captive portal or consult the articles available in our online knowledge base.
