I am trying to set up a SEB with moodle version 3.10 using SEB client config. Everything works just fine with Browser exam key but the problem with this is that students with different OSs are using different versions of SEB (macOS 2.2.2, win10 18.104.22.168, win7 2.4.1, ..) and i need to generate browser key for each version individually. As a solution for this, i tried using config key, which is supposed to verify just the configuration of SEB. In the documentation for moodle 3.10, it says that i can use either of those but it doesnt work for me. Only browser exam key works properly, config key doesnt work. Does anyone have experience with using config key?
