AOS 6.5.2.0 - Captive Portal auto prompt not working on iOS

Hello!

 

I am working currently with an aruba 7030 controller (AOS  6.5.2.0) and a custom internal captive portal page.

 

All sorts of clients except iOS devices open the CP page automatically after association.
I read a mass of topics but found no solution jet.

 

We have no pefng license.
The controller plays dhcp server, default gateway and dns server is a other device.

 

I've enabled the Apple Captive Network Assistant bypass, as suggested in this article:

http://community.arubanetworks.com/t5/Wireless-Access/Automaticly-open-captive-portal-after-joining-unsecured-wifi/m-p/283980

But this has no affect in my case.

 

DNS lookups are possible in the initial role, i've tested this with nslookup.

 

Initial role befor login:

 

#show rights Gast-cp_prof

Valid = 'Yes'
CleanedUp = 'No'
Derived Role = 'Gast-cp_prof'
Up BW:No Limit Down BW:No Limit
L2TP Pool = default-l2tp-pool
PPTP Pool = default-pptp-pool
Number of users referencing it = 2
Periodic reauthentication: Disabled
DPI Classification: Enabled
Youtube education: Disabled
Web Content Classification: Enabled
IP-Classification Enforcement: Enabled
ACL Number = 69/0
Openflow: Disabled
Max Sessions = 65535

Check CP Profile for Accounting = TRUE
Captive Portal profile = Gast-cp_prof

11 any any svc-dhcp permit Low 4

Expired Policies (due to time constraints) = 0

CP profile settings:

I'm grateful for any recommendation.

 

Thank you!

You have a custom page.  Try it with the default captive portal page on the controller.

Hi!

 

I changed captive portal back to the aruba default.
No effect, on ios the cp page don't pop up automatically.

 

Bypass Apple Captive Networ Assistant is disabled.
DNS lookups are successful, http://captive.apple.com/hotspot-detect.html and http://www.apple.com/library/test/success.html are not reachable in the initial role.

 

Do you have another idea?

 

Thank you for help!

 

 

Best regards

Re: AOS 6.5.2.0 - Captive Portal auto prompt not working on iOS

Update:

Now i changed the L3 Authentication captive portal custom profile to "Use HTTP for authentication" AND the default site.
Now CNA pops up.

 

Now i think the error lies in the HTML code from the custom CP page.
Do you know for what i should look for?

 

Thanks for help!

Best regards

Update:

With the exlusion procedure i minimized the CSS code of my html page until the CNA pops up.
I am able to confirm this article now, start with the basics if you want to create a custom captive portal!

I used this guide for my customizations and i must say, you hav to clean out everything of the css codes that is not needed.
Something in the css blocked the CNA. I was not able to find the responsible line, because of time (about 6000 lines in the template).

 

Now the CP pops up automatically on iOS :)
