We have a client running our external captive portal on a ZD3025 v: 9.12.3.0 build 34 and the captive portal is not opening automatically on iOS but only if the user try to access some non enabled site on browser.
He reported us that their controller certificate is invalid.
Could this prevent the captive from opening on iOS devices?
Have you some idea of what could be causing this issue?
This is the walled garden we are using:
