HI! I can log in to my NAS just fine via a browser and I can connect to the file server logging in with my usual credentials and it shows up in my Finder. However, when I try to add the folder I created on my NAS to Time Machine, when it asks me to log in to access the server, I add my credentials, the window disappears for a sec and then pops back up again! Over and over and over. No error message, it doesn't shake its head like when you add the wrong password, it just won't move past that stage and I don't know what to do. Does anyone have any suggestions? So, this first log in window to connect in Finder works great. The second one, the green one, for connecting to the Time Machine, won't follow through. Very frustrating. I followed these instructions here created a new used for Time Machine, enabled smb and everything it asked. But I can't get it to allow me to log on. Once again, no error message occurs, the window disappears and then pops up again in 2 seconds.
