Configure project-specific NTP server

By default, the gateway synchronizes its internal clock with the default Network Time Protocol (NTP) server. If your organization requires a specific NTP server, you can configure the gateway to use a project-specific NTP server using the Signify Interact Builder mobile app and web portal.

Before you begin, ensure that:

  • The gateway is powered on and connected to the network infrastructure.

  • UDP port 123 is open on the network firewall or router to allow communication with the NTP server.

The gateway uses NTP server to synchronize its internal clock, which is required for accurate schedule execution. If the "NTP Server Unreachable" message is displayed, verify that UDP port 123 is open on the network router or firewall and the specified NTP server is available.

Project-specific NTP server configuration using the web portal
