Network Connectivity

Ensure that your network allows communication between the CueCollab server and client devices.
When using ArtNet timecode input, ensure that the necessary ports are open and not blocked by firewalls, routers, or other network devices.

The following ports must be accessible on the CueCollab server machine:

PortProtocolDescription
3000TCP (HTTP)CueCollab Server (required)
3001TCP (WebSocket)CueCollab Realtime (required)
6454UDPArtNet timecode input

This is the main HTTP port for the CueCollab web interface. Client devices connect to this port to access the application.

Firewall rules: Allow incoming TCP connections on port 3000 from client devices on your network.

This WebSocket connection provides real-time updates between the server and client devices, ensuring synchronized data across all connected users.

Firewall rules: Allow incoming TCP connections on port 3001 from client devices on your network.

This UDP port receives ArtNet timecode data. Required only if using ArtNet as your timecode source.

Firewall rules: Allow incoming UDP packets on port 6454 from your ArtNet timecode source.

For license activation and updates, ensure that the application can access the internet:

ServerProtocolDescription
api.mschoeffmann.comTCP/443 (HTTPS)License activation and validation (required)
files.mschoeffmann.comTCP/443 (HTTPS)Update check and downloads

Required for license activation and periodic validation. The application must be able to reach this server at least once every 30 days (depending on license type).

Firewall rules: Allow outgoing HTTPS connections to api.mschoeffmann.com on port 443.

Used to check for application updates and download new versions.

Firewall rules: Allow outgoing HTTPS connections to files.mschoeffmann.com on port 443.

For optimal performance, connect the CueCollab server and all client devices to the same local network using wired (Ethernet) connections.

Recommended:

  • Gigabit Ethernet (1000 Mbps) or faster
  • Dedicated VLAN for production systems (optional but recommended for larger setups)
  • Quality of Service (QoS) configuration to prioritize CueCollab traffic

While CueCollab can work with Wi-Fi clients, wired connections are strongly recommended for:

  • The CueCollab server machine
  • Devices used for critical operations (e.g., showcallers)

Wi-Fi may be acceptable for monitoring-only clients or non-critical users.

Remote access is technically possible but not recommended, as CueCollab currently lacks authentication mechanisms. Additionally, internet connections introduce latency, which is problematic when timecode accuracy is critical.

For secure remote access, Tailscale (a VPN that enables computer sharing similar to file sharing on Dropbox) has proven effective for sharing the server machine with team members.

Remote access may be used experimentally, but only at your own risk.

Do not publish the server to the internet without additional security measures.
