flash not working on 1dx mkII

[tizianmast]

The title says it all, i have a very simple flash, that fires when it gets the middle pin and ground thingy from the hot shue connectet. it works on my other cameras, but somehow not on my 1dx MKII, in both live view and not. I allready cleaned the contacts.  It worket at some pont, but not anymore. the speedlite setting is activated.

i tried with a culmann sl28, but this fires by shorting the midle pin and to ground(the outside of the hotshue, it is a two pin flash) and i tried with the metz 40af-4c this has more pinns, but still fires the same way. i can fire both flashes with a wire or another camera

What happens if you use a Canon speedlite.
