I am unable to message/invite/join a friend ingame. It keeps saying he's offline even though he's online in the friend list and his status changes (playing/menus/lobby) sometimes when i try to invite him it also says "failed due to version mismatch"

 

I am using the steam version of warframe, we both are on pc, my connection is good, his connection is good, i can do everything i mentioned with other players, only it's not working with him.
