Issue Accessing CUPS Administration Page on Raspberry Pi from MacBook

[Ariel-makerist]

I am using a Raspberry Pi 3B with the latest Raspberry Pi OS and have installed CUPS to manage printing. I’ve ensured that all relevant configurations are set, including network access permissions, to allow access from my MacBook. Here’s a summary of my setup and the issue I’m facing:

1.	I installed CUPS and edited the configuration file (/etc/cups/cupsd.conf) to include:

WebInterface Yes

2.	I ensured that Allow directives are set under the <Location /admin> and <Location /admin/conf> sections and confirmed that network access lists are properly configured to enable access from my Mac.
3.	After setting WebInterface to Yes, I restarted the CUPS service.

However, when I access CUPS on my MacBook Air M1 via the IP address, I reach the CUPS home page, but clicking “Administration” returns a message saying to set WebInterface Yes in the config file — which is already set.

Troubleshooting Steps Taken:

•	Verified the configuration in /etc/cups/cupsd.conf, including WebInterface Yes and Allow settings.
•	Restarted the CUPS service (sudo systemctl restart cups).
•	Verified network permissions and confirmed access lists.
•	Checked firewall settings to ensure port 631 is open.
•	Cleared browser cache and used incognito mode.
•	Verified permissions with sudo chown -R root:lp /etc/cups.
•	Checked the CUPS error log, but didn’t find any relevant errors.

Environment:

•	Raspberry Pi 3B
•	Raspberry Pi OS (latest)
•	CUPS version: [insert version number]
•	Accessing from: MacBook Air M1

Question:
Is there anything I may have overlooked in the setup, or are there known compatibility issues with accessing CUPS from an M1 MacBook? Any guidance would be greatly appreciated.
