Workshop inaccessible in Steam Client

[Ivan]

I noticed that yesterday the workshop is inaccessible (and possible a few days before). I can still access my own creations through my profile, but not see the Hazeron workshop anymore. Clicking the button either from the storepage or community hub, just brings you to the general "everything" ("Alles" in Dutch) page.

All workshop items are still accessible ingame, but just not in the Steam client itself. It works fine for another game (Star Wars Empire at War) so it's not a general Steam issue either.
