Player cannot set time using NTP

If your player is having trouble retrieving the time from a Network Time Protocol (NTP) server, it is likely that the firewall on the local network is blocking UDP communications. The Network Time Protocol uses UDP to communicate with time servers, and BrightSign players cannot route these requests through a proxy server like they can with HTTP/HTTPS communications. 

There are a few ways to fix this problem:

  • Configure the firewall on the local network to allow NTP requests to pass through. The player will send NTP requests whether or not it is configured to use an HTTP/HTTPS proxy.
  • Configure the player to use the HTTP Time Protocol (HTP), which can work through most proxies.
  • Run an NTP server instance on the local network. Make sure the player is configured to use this NTP server.

Note: BrightSign players use the Simple Network Time Protocol (SNTP), which is compatible with standard Network Time Protocol (NTP) servers.
