In this article, you will learn about first-level troubleshooting on the cloudi-Fi cloud-based captive portal
1) The Captive Portal doesn’t appear when the visitor connects to the Guest WiFi network
Step 1: Verify the device’s network configuration
-
Does the device get an IP Address from the DHCP server?
If not, verify the DHCP Server or the Layer 2 connectivity between the device and the DHCP Server.
If yes, you can go to the next point.
-
Can the device resolve public FQDN?
Try to resolve login.cloudi-fi.net from the device.
If the device cannot resolve it, verify the connectivity between the device and the DNS Server.
If yes, go to the next point.
-
Access to an HTTP Website.
Try to access an HTTP Website to trigger the captive portal.
Go to http://neverssl.com or http://3wi.fi
- The webpage cannot be displayed: This means there is an issue with the Internet access. If you use our WAN Deployment with VPN, verify the VPN status.
- The Cloudi-Fi Captive Portal appears: The issue may come from the visitor's device, which doesn't perform its connectivity check. Try to restart the device and reconnect to the Guest's WiFi.
- The NeverSSL website appears correctly, meaning your device may have already been authenticated in Cloudi-Fi Captive Portal and is allowed to browse the Internet.
Step 2: Verify Cloudi-Fi Captive Portal availability
-
Connect to Cloudi-Fi Admin interface. Go to Locations and try to display the portal. If you can see the captive, our services are UP and running.

-
If you cannot access to Cloudi-Fi administration interface, try to access https://login.cloudi-fi.net
You should be redirected to http://3wi.fi and see a Cloudi-Fi blue page.
That means Cloudi-Fi services are UP and running.
Step 3: Contact the Cloudi-FI Support team.
Finally, if the problem is not identified, you can contact the Cloudi-Fi Support team via email or chat in the Cloudi-Fi Admin interface.
