"Error contacting server" while login guest portal on Mac

Hi Cambium support team,


I'm having an issue while trying to connect Macbook Air (OS X Yosemite v 10.10.5) to wirless network with guest portal enabled and voucher code as authentication method.

When you connect to the network using wifi password guest portal window come up as on other platforms but when you login using a valid voucher code "Error contacting server" error message apears on the buttom of the screen (see attached screenshot).


This issue apears to occur only on Macs as other Windows\Android\IOS devices on this network doesn't happen to encounter this problem. Connecting this Macbook to other Cambium WiFi networks  with guest portal enabled causes the same issue.





Re: "Error contacting server" while login guest portal on Mac

The issue here is MAC Book IOS started blocking any cross origin requests in their Captive network assist browser or embedded browser which we are calling here. Not sure why they started doing it but this is what’s there now. It used to work few months back but now it doesn’t. We are trying to solve this issue by making some design changes in our solution to avoid triggering any cross origin requests but getting the solution out will take some time, we are actively working on solving this issue and hoping that in next couple of weeks we should be able to roll out the solution. This issue is seen only for MAC Book devices and IPAD/IPhone or any other android/windows devices seem to be working fine. For time being I would suggest that enable Bypass Captive portal config to make things work on all devices, I do understand one does loose the auto pop-up for the Captive portal login but this is what we will have to do for now till the solution is not rolled out.

Thanks for reply, sandeshkumarb


Fortunately we have a small fleet of Macs and it is a local WiFi network. So I'd just witelist them to bypass the portal compleetly for now.
