“Have you tried syncing a project from perforce and attempting to access source control from inside of that project?”

I 've set workspace on Perforce and got latest revision to it. I can connect to cloud stream and do ‘add checkout submit’ etc. Via P4V like a charm but when i open the project and try to get connection by using the same auth, error occures.
