Hi Dominik , Can you go to the connection, then click the "..." to get into the connection settings? Do you see Authentication as certificate? if you click into that, and then Certificate, do you see any certficates installed? Also, if you go to iOS Settings > General, if you scroll down after iTunes Wi-Fi Sync and VPN, you may see "Profiles & Device Management". Do you see any configuration profiles which contain the cert you want to use? If not, how did you get the cert on your device? Regards
