I keep getting
"The webpage at http://connectivitycheck.gstatic.com/generate_204"
error when connecting with some android devices.
I think there was a post on suggesed whitelist settings for IOS and Android captive portal issues but can't seem to find it.
Is this the post you were refering to?
I spoke to soon. I'm getting errors on IOS devices as well.
Note that this is for a Voucher only splash page. No Free, paid or social login.
On IOS, it seems to be trying to go to localhost
Can you Please enable Bypass Captive Portal Detection under Guest Access Page as shown in screenshot attached .
The issue faced by Martin can be fixed by upgrading to 3.5.1. This version is available for upgrade on cnMaestro.
Bypass captive portal will be required if you use social login with Google / Facebook.
It is the android way of detecting if a Captive Portal sign in is required .
The detection url differs between different Android versions.For Marshmallow, it uses connectivitycheck.gstatic.com/generate_204, check the code here AndroidXRef - Marshmallow 6.0.0_r1
For Kitkat, it uses clients3.google.com/generate_204 check the code .
To avoid these popping of webpages we can add these below urls inro whitelist on access point .
