I asked this a while ago but it has not been answered. Any ideas, anyone?
I have a MacMini running PMS and it streams perfectly to Roku. I also used to be able to navigate to an IP address from other devices (Mac or Win laptop, iPhones, etc). Now, when I try to navigate to that IP address, I get a "Sign In or Sign Up" screen. When I enter my password, etc, I get a "user could not authenticated" error. Eventually I get "User could not be authenticated. This IP appears to be having trouble signing in to an account (detected repeated failures)". I am running through an AT&T wireless router (NVG599), if that might matter. Please explain the fix to me (if there is one!) like I'm an idiot, as I don't have much home networking experience.
