We cannot access the ui page for our node-red flows. In experimenting with various methods of trouble shooting, the port :1880 was changed to :1881. When accessing 192.168.0.81:1881 to get to the general node-red flow page, we log in once at the login screen, it works, and then brings us to the main screen. Every time this page is refreshed, we do not need to log back in on the main page but a pop up comes down from the top (see attached screenshot for example of pop up). On this page, if we hit cancel it goes away and we can operate fine. If we try to input our username and password it just pops back up.
When trying to access 192.168.0.81:1881/ui , the same pop up screen appears and still doesn't work when typing in username and password, but when we hit cancel, the page just says "Unauthorized." (see screenshots attached).
