CUPS Unauthorized when using Chrome browser in Ubuntu 18.04

Using Chrome Version 66.0.3359.139 (Official Build) (64-bit)

I am able to access and add a printer through Chrome by going to the page http://localhost:631/admin/login and I can add a printer fine. But I cannot add the printer if I go directly to http://localhost:631/admin and bypass the login. If I need to change any defaults of the printer through the same pages it gives me the "Unauthorized" and will not change anything. I can change it in Firefox and the printers control panel.
