UE4 refuses to find Perforce Workspace

I’m trying to setup Version Control at the moment (because I more or less had to restart due to curropted Structure file) but I encautered a problem.

I know there are probably a few with Perforce problems but I didn’t find anything to fix my problem.

I followed this tutorial exactly (except for the obvious parts):
but UE4 still doesn’t find my workspace and at this point I really have no idea why?

So please help if somebody knows the reason.
