Since the update to macOS Sequoia, you might encounter an error in your browser, specifically in Chrome, when trying to access a resource on your local network, such as a NAS, Plex, or anything else you host yourself.
ERR_ADDRESS_UNREACHABLE To fix this issue, go to “System Settings” -> “Privacy & Security” -> “Local Network” and allow Chrome to “Let the application below find and communicate with devices on your local network”.
This will restore your access, and you will be able to access your internal network resources again.
