I have a very strange problem concerning my server-manager. It's not possible to access it from the local network. Every time I try to open the server-manager I get the authentication mask and whatever user I try to login I get the same message. You entered the wrong password or the user is not correct.
But it's possible to access the server-manager from the outside network. I've entered one static external IP as trusted one's and it possible to login from there, any idea why?
