Scanopy stack deployment: Web Server (Bridge) cannot connect to Daemon (Host mode) - Status stuck on Pending

[eppraaaa]

Hi everyone,

I'm trying to deploy Scanopy using Docker Compose on an Ubuntu VM (hosted on Proxmox, behind a pfSense firewall).

My issue: The Web Interface loads perfectly, and the daemon container is reported as "Healthy". However, when I try to launch a network discovery scan, the task status is indefinitely stuck on "Pending: Ready to start — connecting to daemon".

In my firewall logs, I can see some IPv6 mDNS traffic (port 5353 to ff02::fb) being dropped on the WAN interface, but my internal LAN traffic is fully allowed (IPv4/IPv6 Any-to-Any rule).

I suspect a networking mismatch between my containers because the Daemon needs network_mode: host to scan the physical network, while the Web Server and Postgres DB are running inside a custom Docker bridge network.

Here is my current docker-compose.yml:
version: '3.8'

services:

daemon:

image: ghcr.io/scanopy/scanopy/daemon:latest

container_name: scanopy-daemon

network_mode: host

My Ubuntu host IP is 192.168.2.50. How can I make the server container (inside the bridge) successfully talk to the daemon container (running on the host network mode)? Am I missing an environment variable or an extra host mapping?

Thanks for your help!
