Latest Chrome unauthorized to alter CUPS

I can access CUPS (http://localhost:631/admin), but when I try any Administration tasks such as "add printer. I get this error:

Unauthorized
Enter your username and password or the root username and password to access this page. If you are using Kerberos authentication, make sure you have a valid Kerberos ticket.

Edit "/etc/cups/cupsd.conf"

Change:
<Limit CUPS-Add-Modify-Printer CUPS-Delete-Printer CUPS-Add-Modify-Class CUPS-Delete-Class CUPS-Set-Default CUPS-Get-Devices>
AuthType Default
Require user @SYSTEM
Order deny,allow
</Limit>

To:
<Limit CUPS-Add-Modify-Printer CUPS-Delete-Printer CUPS-Add-Modify-Class CUPS-Delete-Class CUPS-Set-Default CUPS-Get-Devices>
AuthType None
# AuthType Default
# Require user @SYSTEM
Order deny,allow
</Limit>

Did you try entering your username and password, or the root username and password?

Its not available. Just the message appears.

The same issue is ongoing at arch forums:

With Firefox, a login/password prompt pops up. Not with Chrome.

I installed manjaro-printer to test it out, and the dialogue box pops up in both Firefox and Chromium.

Reading the Arch thread apparently Chromium doesn’t work for them so… not sure. Could you try Chromium, and with a Guest user/window? This might point to whether it’s a package thing or a user config thing.

I tried Chromium also. Same result.
