Displayport not working on dock. It works when I connect it to my T420 displayport. Anyone knows what the issue might be? Dock is charging. USB seems not to be working though.

I had similar problem, but with newer dock (ThinkPads xx40-xx70). Something got wrong with device logic and wasn't able to work correctly with particular dock. In order to solve the problem, I had to connect affected laptop to different dock and different laptop to affected dock. After restaring affected laptop and connecting it again to affected dock, it started to work normally again.
