Missed WSUS Updates on Win2012

Hello I installed WSUS on Windows 2012 std, my problem and this, in the configurations I decided I had to download updates on a remote path like this: \ \ server \ wsus. I gave permissions to full control to user domain that is connected to my win2012. I also tried to insert a txt file remotely on this path network and works
Now I get these errors in the event log:
EventID: 12072
