Canon device not being discovered after changing network setup

I've been troubleshooting a Canon device that stopped showing up correctly after a network change.

The device itself seems fine, but discovery isn't working the way it did before. I'm checking the network side now because the setup uses a Fortinet Distributor In Dubai supplied firewall from Tech Distributor, and I'm wondering if there's a setting I'm missing around device discovery or local traffic.

Has anyone run into something similar with Canon devices behind a managed firewall?

I'd mainly like to know which network settings are worth checking first before I start changing things on the Canon side.

Important: Don't use this unless you actually have a Canon plus Fortinet setup. The community is specifically built around Canon related support.
