Hi again Anthony,

I'm very surprised by this, as this has been working reliably for a long time, and no recent changes have happened at all. So I just pulled a Debian Bullseye install and installed CUPS on it; the cupsd.conf file had this in, which makes for a working webinterface:

    # Only listen for connections from the local machine.
    Listen localhost:631
    Listen /run/cups/cups.sock

    # …

    # Web interface setting...
    WebInterface Yes
    
    # Restrict access to the server...
    <Location />
      Order allow,deny
    </Location>

Is your machine really just a Debian Bullseye host? (It feels like it could have been cross-graded from Ubuntu…).

I'd be really curious to hear how you got in this situation, as a default Debian Bullseye with CUPS clearly has working print jobs and an accessible webinterface.

Best,
OdyX
