EAP245 is sometimes showing default captive portal instead of our custom captive portal
I've set up a (custom) captive portal on our access point. However, sometimes it is showing the default captive portal (that page where they should enter an username and password) instead of our custom one. Any idea why it's displaying the wrong captive portal?
My settings (please let me know if any other screenshot is required to give an answer to my problem);
IPs and URLs are correctly set.
Line 1 is set to the IP adress of our Radius server. Line 2 is set to the URL of setting 'external web portal URL' from screenshot 1. Line 3 is set to the IP address of our captive portal.
