This article lists the required firewall ports for Spire to ensure proper system communication.

Firewall Direction Requirements

Allow traffic on:

  • Incoming on the server

  • Outgoing on the workstation (normally allowed by default)

Required Ports

  • PostgreSQL (TCP) for PostgreSQL communication (postgresql.exe) Port 5432 for on-premise and Port 5433 for Spire Cloud

    • Port 5432 for on-premise installations

    • Port 5433 for Spire Cloud deployments

  • Spire Server (TCP) (or as configured on installation) is running the Spire API server needed by Spire Desktop and Spire Web (spired.exe)

    • Port 10880

  • Spire Server (UDP) is used for discovery (even if you configure the API server to listen on another port) (spired.exe)

    • Port 10880

Verify these ports are open on all firewalls and security software to prevent connectivity issues.
