Network and Ports

Blender Camera Controller uses separate local services for control and optional preview configuration.

Crop configuration server Browser-based manual crop setup service

The phone and computer must be on the same reachable LAN. Avoid mobile-data-only phone connections, VPNs, proxies, guest Wi-Fi, client isolation, and restrictive firewalls. Use 5 GHz Wi-Fi where possible; USB tethering can be an alternative.
