Apple IOS Devices are not getting the splash page

Some iOS devices are not automatically redirected to the Captive Portal when the user connects to the WiFi hotspot with a iOS device.

• Double-check that your network equipment does not have a “Bypass Apple CNA” feature. If it does, be sure that the feature is NOT enabled.
• Be sure that the IOS device has “Auto-Login” enabled for the guest network. See this Apple article for more info.
  

  How iOS devices determine if it has an Internet connection

• Devices check for the following domains which are hosted on Akamai network:captive.apple.com
  www.airport.us
  www.thinkdifferent.us
• If the domain is accessible the Captive Portal is not triggered automatically. A “Success” response means the device is connected to the internet.
  

  How to test on iOS

  Make sure you have no active internet session. If you do, wait until your session profile expires.

•  Check Auto-Join and Auto-Login settings
  

  1. Launch the Settings app on your iPhone or iPad.
  2. Tap on Wi-Fi
  3. Tap on the info button next to the network name.
  4. Turn Auto-Join and Auto-Login off
• Associate the device with your WiFi network, but do not connect through the splash page.
• Open regular Safari browser and enter the “captive.apple.com” to the URL
• If you get the “Success”, the Apple’s domain is accessible
  

  Possible Solutions

• Forget the Wi-Fi network
  
  1. Launch the Settings app on your iPhone or iPad.
  2. Tap on Wi-Fi.
  3. Tap on the info button next to the network name.
  4. Tap on Forget This Network.
• Restart you iOS Device. Based on our experiences, restarting the iOS device should resolve the issue with CNA (Captive Network Assistant)
• Launch iOS Settings, then General tab > Reset and select Reset Network Settings.
  This will delete all network settings, returning them to factory defaults.
• Check your Walled Garden settings or your Firewall Policy.The akamaihd.net and akamai.net domain and IP addresses have to be inaccessible to unauthenticated users
