The captive portal is not showing

Understand the root cause to understand why a captive portal is not showing when you’re connected to the Guest SSID

When guests attempt to connect to the SSID, if the captive portal isn’t showing up when connected to the Guest SSID, it could be due to various issues that prevent the proper captive portal display.

Several possible causes may trigger this error page, including:

• DHCP or DNS issue

• The device is not performing automatic detection requests

• Misconfiguration of the walled garden

• Firewall rules 

To address this issue, several actions can be taken:

• Checking if the private IP address is valid 

• Trying to resolve login.cloudi-fi.net

• If valid IP and DNS working

  • Trying to visit http://neverssl.com. This should trigger the captive portal.

  • Checking firewall rules 

    Source	Destination	Port	Protocol	Action	Comment
    Guest Subnet	DNS	53	UDP/TCP	Allow	DNS Resolution
    Guest Subnet	HTTP	80	TCP	Allow	HTTP Traffic
    Guest subnet	HTTPS	443	TCP	Allow	HTTPS resolution

    
    

    • If the captive portal is still not reachable:

      1. Check the walled garden and add at least Cloudi-Fi's domains 

      2. Run a Wireshark capture

      3. Screenshot web browser error if there is any

      4. Share the captures with Cloudi-Fi Support Team

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

If you are still experiencing the error page issue after following these recommended actions, don't hesitate to get in touch with 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.
