Secure https:// site with invalid or self-signed security certificate won’t load?

By default, Kiosk Pro is based on Apple's UIWebView browser, which is built into the iOS operating system. UIWebView does not have the ability to bypass authentication for untrusted security certificates. On iOS, invalid, expired, and self-signed security certificates are all considered untrusted.  

We offer the option of an alternate browsing engine, WKWebView. WKWebView allows you to bypass authentication of security certificates on a case by case basis through a ‘Continue’/’Cancel’ popup.

You can confirm the problem (and get more details about what is going on) with the certificates on your site by visiting the site in another browser. If you have visited the site previously in this browser and accepted the untrusted certificate, you will have to clear the previous exception to view the error (which is not currently possible in mobile Safari).  In Firefox desktop, you can do this by going to Options > Advanced > Encryption > View Certificates > Servers and find your site in the resulting list, highlight it, and 'Delete'. You can then navigate to the site in the Firefox browser again to trigger the certificate error.

To use your page with Kiosk Pro, you will either need to place it on an unsecured server (one with an http:// prefix), provide a trusted security certificate, or use the WKWebView browsing engine included in Plus and Enterprise.
